Pin Configuration

-

The APL5610/A is a low dropout linear regulator controller.

The APL5610/A could drive an external N-Channel

MOSFET and provides an adjustable output by using an

external resistive divider.

The APL5610/A integrates various functions. For example,

a Power-On-Reset (POR) circuit monitors VCC supply

voltage to prevent wrong operations; the function of Un-

der-Voltage Protection (UVP) protects the device from short

circuit condition. A POK indicates that the output status

with time delay which is set internally. It can control other

converter for power sequence. Moreover, the APL5610/A

can be enabled by other power system; namely, holding

the EN above 1.6V enables output and pulling the EN

under 0.4 disables output.

The APL5610/A is available in SOT-23-6 package.
