General Description
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.
