MP2009
Ultra-Low-Noise
Low-Dropout, 120mA Linear Regulator
The Future of Analog IC Technology
DESCRIPTION
FEATURES
The MP2009 is an ultra low noise, low dropout
linear regulator. The output voltage of MP2009
ranges from 1.5V to 4.5V in 100mV increments
and 1% accuracy by operating from a +2.0V to
+6.0V input. It is designed to deliver up to
120mA continuous output current. It achieves a
low 120mV dropout for full load current.

Low 50µA Ground Current
The MP2009 uses an internal PMOS as the
pass element, which consumes 50µA supply
current at no load condition. New innovative
design techniques make MP2009 achieve ultra-

APPLICATIONS
The MP2009 are designed and optimized to
work with low value, low cost ceramic
capacitors in space-limiting and performance
consideration. It requires only 1µF (typ) of
output capacitance for stability with any load.
It is available in a 5-pin SC70 package.

MP2009-ULTRA LOW NOISE, LOW DROPOUT,120mA LINEAR REGULATOR
OPERATION
The MP2009 is an ultra low noise, low dropout,
low-quiescent current linear regulator designed
for space-restricted applications. It is intended for
use in devices that requires very low voltage, low
quiescent current such as wireless LAN, battery-
powered equipment and hand-held equipment.
Shutdown
The MP2009 can be switched ON or OFF by a
logic input at the EN pin. A high voltage at this
pin will turn the device on. When the EN pin is
low, the regulator output is off. The EN pin should
be tied to VIN to keep the regulator output always
on if the application does not require the
shutdown feature. Do not float the EN pin.
Internal P-Channel Pass Transistor
The MP2009 features
a
1.4Ω P-channel
MOSFET as the pass transistor. It provides
several advantages over similar designs using
PNP pass transistor. The P-channel MOSFET
requires no base drive, which reduces quiescent
current considerably and increase the battery life.
PNP-based regulators waste considerable
current in dropout when the pass transistor
saturates. They also use high base-drive current
under the large load condition. The MP2009 does
not suffer from these problems and consume
only 50µA of quiescent current in light load and
dropout mode.
Current Limit and Thermal Protection
The MP2009 includes an independent current
limit structure which monitors and controls the P-
channel MOSFET’s gate voltage to limit the
guaranteed maximum output current to 120mA.
Thermal protection turns off the P-channel
MOSFET when the junction temperature exceeds
+150ºC, allowing the IC to cool. When the IC’s
junction temperature drops by 20ºC, the PMOS
will be turned on again. Thermal protection limits
total power dissipation in the MP2009. For
reliable operation, junction temperature should
be limited to 125 ºC maximum.
Dropout Voltage
Dropout voltage is the minimum input to output
differential voltage required for the regulator to
maintain an output voltage within 100mV of its
nominal value. It determines the available end-of-
life battery voltage in battery-powered systems.
For the P-channel MOSFET pass element, the
dropout voltage is a function of drain to source on
resistance. Because the P-channel MOSFET
pass element behaves as a low-value resistor,
the dropout voltage of MP2009 is very low.

APPLICATION INFORMATION
Power Dissipation
bypass capacitor for space-limiting applications.
The power supply rejection is 75dB at 10kHz and
55dB at 100kHz. (See the PSRR vs. Frequency
The power dissipation for any package depends
on the thermal resistance of the case and circuit
board, the temperature difference between the
junction and ambient air, and the rate of airflow.
The power dissipation across the device can be
represented by the equation:
graph
in
the
Typical
Performance
Characteristics).
Input Capacitor Selection
Use a 1µF capacitor on the input of the MP2009.
Larger values will help to improve line transient
response with the drawback of increased size.
Ceramic capacitors are preferred, but tantalum
capacitors may also suffice.
P = (VIN - VOUT) ×IOUT
The allowable power dissipation can be
calculated using the following equation:
P(MAX) = (TJunction - TAmbient) / θJA
Output Capacitor Selection
Where (TJunction - TAmbient) is the temperature
difference between the junction and the
surrounding environment, θJA is the thermal
resistance from the junction to the ambient
environment. Connecting the GND pin of
MP2009 to ground with a large ground plane will
help the channel heat away.
The MP2009 is designed specifically to work with
very low ESR ceramic output capacitor in space-
limiting and performance consideration. Output
capacitor of larger values will help to improve
load transient response and reduce noise with
the drawback of increased size. A 1µF ceramic
capacitor with ESR lower than 3Ω is sufficient for
the MP2009 application circuit. (See the Region
of Stable COUT ESR vs. Load Current graph in the
Typical Performance Characteristics)
Output Noise and PSRR
For the MP2009, an internal 50pF bypass
capacitor with new innovative structure reduces
output noises greatly. It does not need external

PCB LAYOUT GUIDE
PCB layout is very important to achieve good
regulation, ripple rejection, transient response
and thermal performance. It is highly
recommended to duplicate EVB layout for
optimum performance.
2) Ensure all feedback connections are short
and direct. Place the feedback resistors and
compensation components as close to the
chip as possible.
3) Connect IN, OUT and especially GND
respectively to a large copper area to cool
the chip to improve thermal performance and
long-term reliability.
If change is necessary, please follow these
guidelines and take figure 2 for reference.
1) Input and output bypass ceramic capacitors
are suggested to be put close to the IN Pin
and OUT Pin respectively.
