The MPQ20056 is a low-dropout linear regulator
that supplies up to 250mA current with a 100mV
dropout voltage and can operate from 2.5V to
5.5V input. The output voltage is preset at 1.8V,
2.5V or 3.3V for the two different packages. An

MPQ20056 – LOW-NOISE, HIGH-PSRR, 250mA LINEAR REGULATOR, AEC-Q100 QUALIFIED
OPERATION
The MPQ20056 is a low-dropout linear regulator
that can supply up to 250mA current, which
makes it suitable for very low voltage, low
quiescent, low noise, and high PSRR
applications, such as wireless LAN transceivers,
notebook computers, smartphones, and other
low-power electronics.
Current Limit
The MPQ20056 includes a current limit structure
that monitors and controls the PMOS gate
voltage to limit the guaranteed maximum output
current to 0.4A.
Thermal Protection
Thermal protection turns off the PMOS when the
junction temperature exceeds 150°C, allowing
the IC to cool. When the IC’s junction
temperature drops by 20°C, the PMOS will turn
on again. Thermal protection limits total power
dissipation in the MPQ20056. For reliable
operation, limit the junction temperature to a
maximum of 125°C.
The MPQ20056 uses an internal PMOS as the
pass element and includes both thermal
shutdown and an internal current-limiting circuit.
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.
Load-Transient Considerations
The output response of the load-transient
consists of a transient response and DC shift—
the MPQ20056’s excellent load regulation
effectively limits the DC shift. The output voltage
transient depends on the output capacitor’s value
and ESR. Increasing the capacitance and
decreasing the ESR will improve the transient
response.
Shutdown
The MPQ20056 can be switched ON or OFF by a
logic input at the EN pin: Logic high turns the
regulator on and logic low turns it off. Tie the EN
pin to VIN if the application does not require the
shutdown feature. Do not float the EN pin.

MPQ20056 – LOW-NOISE, HIGH-PSRR, 250mA LINEAR REGULATOR, AEC-Q100 QUALIFIED
APPLICATION INFORMATION
Setting the Output Voltage
The allowable power dissipation can be
calculated using the following equation:
The output voltage of the MPQ20056 is preset to
1.8V, 2.5V or 3.3V by internal resistor divider.
The output voltage also can be adjusted by using
an external resistor divider (R1 and R2 in Figure
2).
P
=
(
TJunction − TAmbient / θJA
)
(MAX)
Where (TJunction − TAmbient) is the temperature
differential between the junction and the
surrounding environment, θJA is the thermal
resistance from the junction to the ambient
environment. Connecting the exposed GND pad
to a large ground pad or plane helps to channel
away heat.
VOUT
R1
FB
MPQ20056
Output Capacitor Selection
R2
The MPQ20056 is specifically designed to work
with a standard ceramic output capacitor to save
space and improve performance. Use a 4.7µF
ceramic capacitor for most applications. Larger
output capacitors will improve load transient
response and reduce noise at the cost of
increased size.
GND
Figure 2: Setting the Output Voltage
However, the sum of R1 and R2 should not
exceed 10kΩ to minimize their impact on the
internal resistor divider. For an accurate output-
voltage setting, use 1kΩ (±1%) for R2, and
determine R1 with:
VOUT − VFB
R1 = R2×
VFB
For example, for a 1.1V output voltage, R2 is
1kΩ, and R1 is 374Ω. You can select a standard
374Ω (±1%) resistor for R1.
Power Dissipation
The power dissipation for any package depends
on the thermal resistance of the case and circuit
board, the temperature differential between the
junction and ambient air, and the rate of air flow.
The power dissipation across the device can be
represented by the equation:
P =
(
V
IN − VOUT ×IOUT
)
