The APL5610 serise is a low dropout linear regulator
controller.
The APL5610 serise could drive an external N-Channel
MOSFET and provides an adjustable output by using an
external resistive divider.
The APL5610 serise integrates various functions. For
example, a Power-On-Reset (POR) circuit monitors VCC
supply voltage to prevent wrong operations; the function
of Under-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 con-
trol other converter for power sequence. Moreover, the
APL5610 serise 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 serise is available in a SOT-23-6 package.
