MP20043
Dual Channel, 300mA Linear
Regulator With Programmable
Output Voltage and Output Discharge
The Future of Analog IC Technology
DESCRIPTION
FEATURES
The MP20043 is a dual-channel, low noise, low
dropout and high PSRR linear regulator with
programmable output voltage. The output
voltage of MP20043 ranges from 1.2V to 3.3V
in 100mV increments and 2.5% accuracy by
operating from a +2.5V to +5.5V input. The
different output voltage options can be
programmed by setting the voltage of P1 and
P2 to VDD, GND or floating. There are 9
different voltage settings in one chip. Each
output channel can supply up to 300mA of load
current.
The MP20043 uses two internal PMOSs as the
pass devices, which consumes 150μA supply
current when both channels are enabled at no
load condition. The EN1 and EN2 pins control
each output respectively. When both channels
shutdown simultaneously, the chip turns off and
consumes nearly zero operation current which
is suitable for battery-power devices. The
MP20043 also features current limiting and over
temperature protection.

Notes:
Power Dissipation, PD @ TA =25°C,
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature TJ(MAX), the junction-to-
ambient thermal resistance θJA, and the ambient temperature
TA. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by PD(MAX)=(TJ(MAX)-
TA)/ θJA. Exceeding the maximum allowable power dissipation
will cause excessive die temperature, and the regulator will go
into thermal shutdown. Internal thermal shutdown circuitry
protects the device from permanent damage.

MP20043 –DUAL-CHANNEL, 300mA LDO WITH PROGRAMMABLE OUTPUT VOLTAGE
OPERATION
The MP20043 integrates two low noise, low
dropout, low quiescent current and high PSRR
linear regulators. It is intended for use in
devices that require very low voltage, low
quiescent current power such as wireless LAN,
battery-powered equipment and hand-held
equipment. Output voltages are optional
ranging from 1.2V to 3.3V, and each channel
can supply current up to 300mA. The part uses
internal PMOSs as the pass elements and
features internal thermal shutdown and internal
current limit circuits.
tied to VIN to keep the regulator output always
on if the application does not require the
shutdown feature. Do not float the EN pins.
Current Limit
The MP20043 includes two independent current
limit structures which monitor and control each
PMOS’s gate voltage limiting the guaranteed
maximum output current to 490mA.
Thermal Protection
Thermal protection turns off the PMOS when
the junction temperature exceeds +140ºC,
allowing the IC to cool. When the IC’s junction
temperature drops by 10ºC, the PMOS will be
turned on again. Thermal protection limits total
power dissipation in the MP20043. For reliable
operation, the 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. Because the PMOS pass
element behaves as a low-value resistor, the
dropout voltage of MP20043 is very low.
Internal P-Channel Pass Device
The MP20043 features dual typical 0.6ꢀ P-
channel MOSFET pass devices. It provides
several advantages over similar designs using
PNP pass transistors, including longer battery
life.
Shutdown
The MP20043 has two EN pins to control each
channel respectively. And each channel 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

MP20043 –DUAL-CHANNEL, 300mA LDO WITH PROGRAMMABLE OUTPUT VOLTAGE
APPLICATION INFORMATION
Input capacitor of larger value will help improve
line transient response with the drawback of
increased size. Ceramic capacitors are
preferred, but tantalum capacitors may also
sufficient.
Output Voltage
The output
voltage
of
MP20043
is
programmable with setting different states of P1
PIN and P2 PIN. For combination A, the setting
rule is as the following table:
Output Capacitor Selection
Table 1 Programmable Output Voltage
Setting (Combination A)
The MP20043 is designed specifically to work
with very low ESR ceramic output capacitor in
space-saving and performance consideration. A
ceramic capacitor in the range of 0.47µF and
10µF, and with ESR lower than 1ꢀ is suitable
for the MP20043 application circuit. Output
capacitor of larger values will help to improve
load transient response and reduce noise with
the drawback of increased size.

For example, when P1 and P2 are both open,
output voltage of channel 1 is 2.8V, and the
output voltage of channel 2 is 3.3V.
Power Dissipation
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:
P = (VIN - VOUT) ×IOUT
The allowable power dissipation can be
calculated using the following equation:
P(MAX) = (TJunction - TAmbient) / θJA
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. Connect the GND pin of MP20043
to ground using a large pad or ground plane
helps to channel heat away.
Input Capacitor Selection
Using a capacitor whose value is >0.47µF on
the MP20043 input and the amount of
capacitance can be increased without limit.
