600mA, Low Quiescent Current, Fast Transient
Low Dropout Linear Regulator
Description
Pin Assignments
The AP7365 is a 600mA, adjustable and fixed output voltage,
low dropout linear regulator. The device included pass
element, error amplifier, band-gap, current limit and thermal
shutdown circuitry. The device is turned on when EN pin is
set to logic high level.
The characteristics of low dropout voltage and low quiescent
current make it suitable for low power applications, for
example, battery powered devices. The typical quiescent
current is approximately 35μA. Built-in current-limit and
thermal-shutdown functions prevent IC from damage in fault
conditions.
This device is available with adjustable output from 0.8V to
5.0V, and fixed version with 0.8V, 1.0V, 1.2V, 1.5V, 1.8V,
2.0V, 2.5V, 2.8V, 3.0V, 3.3V and 3.9V outputs. Please
contact your local sales office for any other voltage options.
The AP7365 is available in SOT25, SOT89/R-3L, SOT223/R-
3L, and DFN2020-6 packages.

Application Note
Input Capacitor
A 1μF ceramic capacitor is recommended between IN and GND pins to decouple input power supply glitch and
noise. The amount of the capacitance may be increased without limit. This input capacitor must be located as
close as possible to the device to assure input stability and reduce noise. For PCB layout, a wide copper trace is
required for both IN and GND pins. A lower ESR capacitor type allows the use of less capacitance, while higher
ESR type requires more capacitance.
Output Capacitor
The output capacitor is required to stabilize and improve the transient response of the LDO. The AP7365 is stable
with very small ceramic output capacitors. Using a ceramic capacitor value that is at least 1μF with ESR > 15mΩ
on the output ensures stability. Higher capacitance values help to improve line and load transient response. The
output capacitance may be increased to keep low undershoot and overshoot. Output capacitor must be placed as
close as possible to OUT and GND pins.
