AP7361C
1A LOW DROPOUT ADJUSTABLE AND FIXED-MODE REGULATOR WITH ENABLE
Description
The AP7361C is a 1A, adjustable and fixed output voltage, ultra-low
dropout linear regulator with enable. The device includes pass
element, error amplifier, band-gap reference, current limit and thermal
shutdown circuitry. The device is turned on when EN pin is set to logic
high level.
The characteristics of the low dropout voltage and low quiescent
current make it suitable for low to medium power applications, for
example, laptop computers, audio and video applications and battery
powered devices. The typical quiescent current is approximately
60µA. Built-in current-limit and thermal-shutdown functions prevent
IC from damage in fault conditions.

Notes: 7. Dropout voltage is the voltage difference between the input and the output at which the output voltage drops 2% below its nominal value. This parameter
only applies to output voltages above 1.2V since minimum VIN = 2.2V.
8. For VIN 2.5V and VIN = VOUT +1V. For VIN < 2.5V, the PSRR performance may be reduced.
9. Test condition: U-DFN3030-8, SO-8EP devices are mounted on 2"x2", FR-4 substrate PCB, with minimum recommended pad on top layer and thermal
vias to bottom layer ground plane. TO252 devices are mounted on 2"x2" FR-4 substrate PC board, 2oz copper, with minimum recommended pad layout.
For SOT223, the device is mounted on FR-4 substrate PC board, with minimum recommended pad layout. SOT89-5 devices are mounted on 1"x1" FR-4
substrate PC board, with minimum recommended pad layout.

AP7361C
Adjustable Operation
The AP7361C provides output voltage from 0.8V to 5.0V through external resistor divider as shown below.

The output voltage is calculated by:
VOUT

Adjustable Output
Where VREF = 0.8V (the internal reference voltage)
Rearranging the equation will give the following that is used for adjusting the output to a particular voltage:

To maintain the stability of the internal reference voltage, R2 needs to be kept smaller than 80k.
