MIC5501/2/3/4
300 mA Single Output LDO in Small Packages
Features
General Description
• Input Voltage Range: 2.5V to 5.5V
The MIC5501/2/3/4 is an advanced general-purpose
LDO ideal for powering general-purpose portable
devices. The MIC5501/2/3/4 family of products
provides a high-performance 300 mA LDO in an
ultra-small 1 mm x 1 mm package. The MIC5502 and
MIC5504 LDOs include an auto-discharge feature on
the output that is activated when the enable pin is low.
The MIC5503 and MIC5504 have an internal pull-down
resistor on the enable pin that disables the output when
the enable pin is left floating. This is ideal for
applications where the control signal is floating during
processor boot up.
• Fixed Output Voltages from 1.0V to 3.3V
• 300 mA Guaranteed Output Current
• High Output Accuracy (±2%)
• Low Quiescent Current: 38 μA

Note 1: Regulation is measured at constant junction temperature using low duty cycle pulse testing. Changes in
output voltage due to heating effects are covered by the thermal regulation specification.
2: Dropout voltage is defined as the input-to-output differential at which the output voltage drops 2% below its
nominal value measured at 1V differential. For outputs below 2.5V, dropout voltage is the input-to-output
differential with the minimum input voltage 2.5V.
3: Ground pin current is the regulator quiescent current. The total current drawn from the source is the sum
of the load current plus the ground pin current.

Note 1: The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable
junction temperature and the thermal resistance from junction to air (i.e., TA, TJ, JA). Exceeding the
maximum allowable power dissipation will cause the device operating junction temperature to exceed the
maximum +125°C rating. Sustained junction temperatures above +125°C can impact the device reliability.

Enable/Shutdown

APPLICATION INFORMATION
The MIC5501/2/3/4 each come with an active-high
enable pin that allows the regulator to be disabled.
Forcing the EN pin low disables the regulator and
sends it into an off mode current state drawing virtually
zero current. When disabled, the MIC5502 and
MIC5504 switches an internal 25ꢀ load on the
regulator output to discharge the external capacitor.
MIC5501/2/3/4 are low-noise 300 mA LDOs. The
MIC5502 and MIC5504 include an auto-discharge
circuit that is switched on when the regulator is
disabled through the enable (EN) pin. The MIC5503
and MIC5504 have an internal pull-down resistor on the
EN pin to ensure the output is disabled if the control
signal is tri-stated. The MIC5501/2/3/4 regulators are
fully protected from damage due to fault conditions,
offering linear current limiting and thermal shutdown.
The MIC5501/2/3/4 is not suitable for RF transmitter
systems.
Forcing the EN pin high enables the output voltage.
The MIC5501 and MIC5502 enable pin uses CMOS
technology and the EN pin cannot be left floating; a
floating EN pin may cause an indeterminate state on
the output. The MIC5503 and MIC5504 have an
internal pull-down resistor on the enable pin to disable
the output when the enable pin is floating.
4.1
Input Capacitor
The MIC5501/2/3/4 are high performance, high
bandwidth devices. An input capacitor of 1 μF is
required from the input to ground to provide stability.
Low-ESR ceramic capacitors provide optimal
performance at a minimum of space. 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.
X5R or X7R dielectrics are recommended for the input
capacitor. Y5V dielectrics lose most of their
capacitance over temperature and are therefore, not
recommended.
4.5
Thermal Considerations
The MIC5501/2/3/4 are designed to provide 300 mA of
continuous current in a very small package. Maximum
ambient operating temperature can be calculated
based on the output current and the voltage drop
across the part. For example if the input voltage is 3.6V,
the output voltage is 2.8V, and the output current is
300 mA. The actual power dissipation of the regulator
circuit can be determined using Equation 4-1:
EQUATION 4-1:
4.2
Output Capacitor
PD = V IN – V OUT 1 IOUT + V IN IGND
The MIC5501/2/3/4 require an output capacitor of 1 μF
or greater to maintain stability. The design is optimized
for use with low-ESR ceramic chip capacitors. High
ESR capacitors are not recommended because they
may cause high frequency oscillation. The output
capacitor can be increased, but performance has been
optimized for a 1 μF ceramic output capacitor and does
not improve significantly with larger capacitance.
Because this device is CMOS and the ground current
is typically <100 μA over the load range, the power
dissipation contributed by the ground current is < 1%
and can be ignored for this calculation:
EQUATION 4-2:
X7R/X5R dielectric-type 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 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 capacitor to ensure the same
minimum capacitance over the equivalent operating
temperature range.
PD = 3.6V – 2.8V 300mA = 0.240W
To determine the maximum ambient operating
temperature
of
the
package,
use
the
junction-to-ambient thermal resistance of the device
and Equation 4-3:
EQUATION 4-3:
4.3
No-Load Stability

J MAX – T A
PDMAX = ----------------------------------

Unlike many other voltage regulators, the
MIC5501/2/3/4 remain stable and in regulation with no
load. This is especially important in CMOS RAM
keep-alive applications.
Where:
TJ(MAX) = 125°C, the max. junction temp. of the die.
θJA = Thermal resistance of 250°C/W for the DFN
package.
DS20006006B-page 10
2019 Microchip Technology Inc.
MIC5501/2/3/4
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 250°C/W.
The maximum power dissipation must not be exceeded
for proper operation.
For example, when operating the MIC5501-YMT at an
input voltage of 3.6V and 300 mA load with a minimum
footprint layout, the maximum ambient operating
temperature TA can be determined as follows:
EQUATION 4-4:
0.240W = 125C – T A 250C/W
T A = 65C
Therefore, the maximum ambient operating
temperature allowed in a 1 mm × 1 mm DFN package
is 65°C. For a full discussion of heat sinking and
thermal effects on voltage regulators, refer to the
“Regulator Thermals” section of Microchip’s Designing
with Low-Dropout Voltage Regulators handbook.

Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
Information contained in this publication regarding device
applications and the like is provided only for your convenience
and may be superseded by updates. It is your responsibility to
ensure that your application meets with your specifications.
