MIC47053
500mA Micropower ULDO™
Linear Regulator
General Description
Features
The MIC47053 is a high-speed, adjustable output ultra-low
dropout, dual NMOS ULDO™ designed to power point-of-
load applications that require a low-voltage, high-current
power supply. The MIC47053 can source 500mA of output
current while only requiring a 1µF ceramic output capacitor
for stability. The MIC47053 offers 2% output voltage
accuracy over temperature, low dropout voltage (49mV @
500mA), and low ground current which makes this device
ideally suited for mobile and point-of-load applications.
Wide input voltage range
– Input voltage: 1.0V to 3.6V
– Bias voltage: 2.3V to 5.5V
Adjustable output voltage range down to 0.4V
Low dropout voltage of 49mV at 500mA
Low shutdown current: 0.1µA typical
±2% initial output voltage accuracy over temperature
High bandwidth – very fast transient response
Stable with a 1µF ceramic output capacitor
Logic level enable input
The MIC47053 has an NMOS output stage offering very
low output impedance. The NMOS output stage makes for
a unique ability to respond very quickly to sudden load
changes such as that required by a microprocessor, DSP
or FPGA. The MIC47053 consumes little quiescent current
and therefore can be used for driving the core voltages of
mobile processors and post regulating a core DC/DC
converter in any processor.

MIC47053
Functional Description
The MIC47053 is a high-speed, ultra-low dropout,
NMOS ULDO designed to take advantage of point-of-
load applications that use supply rails to generate a low-
voltage, high-current power supply. The MIC47053 can
source 0.5A of output current while only requiring a 1µF
ceramic output capacitor for stability. The MIC47053
regulator is fully protected from damage due to fault
conditions, offering linear current limiting and thermal
shutdown.
Tantalum capacitors have a very stable dielectric (10%
over their operating temperature range) and can also be
used with this device.
Output Capacitor
The MIC47053 requires an output capacitor of 1µF or
greater to maintain stability. The design is optimized for
use with low-ESR ceramic chip capacitors. High-ESR
capacitors may cause high-frequency oscillation. The
output capacitor can be increased, but performance has
been optimized for a 1µF ceramic output capacitor and
does not improve significantly with larger capacitance.
(See the Typical Characteristic section for examples of
load transient response).
Bias Supply Voltage
VBIAS, requiring relatively light current, provides power to
the control portion of the MIC47053. Bypassing on the
bias pin is recommended to improve performance of the
regulator during line and load transients. Small 0.1µF
ceramic capacitors from VBIAS-to-ground help reduce
high frequency noise from being injected into the control
circuitry from the bias rail and are good design practice.
The output capacitor type and placement criteria are the
same as the input capacitor. See the “Input Capacitor”
subsection for a detailed description.
Minimum Load Current
Input Supply Voltage
The MIC47053, unlike most other regulators, does not
require a minimum load to maintain output voltage
regulation.
VIN provides the supply to power the LDO. The minimum
input voltage is 1.0V. This allows conversion from low
voltage supplies to reduce the power dissipation in the
pass element.
Adjustable Regulator Design
The MIC47053 allows programming of the output voltage
with external resistors. The R2 resistor connected
between the ADJ pin and ground should not exceed
10kꢀ, as larger values can cause instability. R1
connects between the ADJ pin and the OUT pin. The
resistor values are calculated as follows:
Input Capacitor
The MIC47053 is a high-performance, high bandwidth
device. Therefore, it requires a well-bypassed input
supply for optimal performance. A 1µF capacitor is the
minimum required for stability. A 10µF ceramic capacitor
is recommended for most applications, especially if the
LDO’s headroom (VIN –VOUT) is small and/or large load
transients are present. Fast load transient and low
headroom requires a larger input filter capacitor to
ensure that the regulator does not drop out of regulation.
A 10µF will better attenuate any voltage glitches from
exceeding the maximum voltage rating of the part.
V
OUT
0.4V
R1 R2

Where VOUT is the desired output voltage and 0.4V is the
internal reference voltage.
Additional high-frequency capacitors, such as small-
valued NPO dielectric-type capacitors, help filter out
high-frequency noise and are good practice in any RF-
based circuit.
Enable/Shutdown
The MIC47053 comes with a single active-high enable
pin that allows the regulator to be disabled. Forcing the
enable pin low disables the regulator and sends it into a
“zero” off-mode-current state. In this state, current
consumed by the regulator goes nearly to zero. Forcing
the enable pin high enables the output voltage.
X7R and X5R dielectric ceramic capacitors are
recommended
because
of
their
temperature
performance. X7R-type capacitors change capacitance
by 15% over their operating temperature range and are
the most stable type of ceramic capacitors. Z5U and
Y5V dielectric capacitors are not recommended since
they change value by as much as 50% and 60%
respectively over their operating temperature ranges. To
use a ceramic-chip capacitor with Y5V dielectric, the
value must be much higher than an X7R ceramic or a
tantalum capacitor to ensure the same capacitance
value over the operating temperature range.

To determine the maximum ambient operating
temperature of the package, use the junction-to-ambient
thermal resistance of the device and the following basic
equation:
Power Good (PGOOD)
The Power Good (PGOOD) pin is an open drain output
that goes low when the output voltage (fixed version)
drops below the PGOOD threshold voltage.
The pull-up resistor value should be large enough to
guarantee a proper “low” voltage when the PGOOD pin
pulls low. The PGOOD low voltage is typically 0.1V at

A
10k resistor or greater is

TJ(MAX) = 125°C, the maximum junction temperature of
the die.
If the PGOOD function is not required, the PGOOD pin
may be left unconnected.
θ
JA thermal resistance = 90°C/W.
Thermal Shutdown
The MIC47053 has an internal over-temperature
protection feature. This feature is for protection only.
The device should never be intentionally operated near
this temperature as this may reduce long term reliability.
The device will turn off when the over-temperature
threshold is exceeded. A 20°C hysteresis is built in to
allow the device to cool before turning back on.

The MIC47053 is designed to provide 0.5A of continuous
current in a very small package. Maximum ambient
operating temperature can be calculated based upon the
output current and the voltage drop across the part.
Given that the input voltage is 1.8V, the output voltage is
1.2V and the output current is 0.5A. The actual power
dissipation of the regulator circuit can be determined
using the equation:
Table 1. Thermal Resistance
Substituting PD for PD(max) and solving for the ambient
operating temperature will give the maximum operating
conditions for the regulator circuit. The junction-to-
ambient thermal resistance for the minimum footprint is
90°C/W. The maximum power dissipation must not be
exceeded for proper operation. For example, when
operating the MIC47053-1.2YMT at an input voltage of
1.8V and a 0.5A load with a minimum footprint layout,
the maximum ambient operating temperature TA can be
determined as follows:

Thermal Measurements
Measuring the IC’s case temperature is recommended to
ensure it is within its operating limits. Although this might
seem like a very elementary task, it is easy to get
erroneous results. The most common mistake is to use
the standard thermal couple that comes with a thermal
meter. This thermal couple wire gauge is large, typically
22 gauge, and behaves like a heatsink, resulting in a
lower case measurement.
Two methods of temperature measurement are using a
smaller thermal couple wire or an infrared thermometer.
If a thermal couple wire is used, it must be constructed
of 36 gauge wire or higher (smaller wire size) to
minimize the wire heat-sinking effect.
In addition, the thermal couple tip must be covered in
either thermal grease or thermal glue to make sure that
the thermal couple junction is making good contact with
the case of the IC. Omega brand thermal couple (5SC-
TT-K-36-36) is adequate for most applications.
Wherever possible, an infrared thermometer is
recommended. The measurement spot size of most
infrared thermometers is too large for an accurate
reading on a small form factor ICs. However, a IR
thermometer from Optris has a 1mm spot size, which
makes it a good choice for the 2mm x 2mm Thin DFN
package. An optional stand makes it easy to hold the
beam on the IC for long periods of time.
