General Description

The APL5932A/B/C/D is a 3A ultra low dropout linear

regulator. The IC needs two supply voltages, one is a

control voltage (V

a main supply Voltage(V

duce power dissipation and provide extremely low drop-

out voltage.

The APL5932A/B/C/D integrates many functions. A Power-

On-Reset (POR) circuit monitors both supply voltages on

V

functions of thermal shutdown and current-limit protect

the device against thermal and current over-loads. A POK

indicates that the output voltage status with a delay time

set internally. It can control other converter for power

sequence. APL5932A/B/C/D can be enabled by other

power systems. Pulling and holding the EN voltage be-

low 0.4V or ENB above 1.2V will shuts off the output.

The APL5932A/B/C/D is available in a SOP-8P package

which features small size as SOP-8 and an Exposed

Pad to reduce the junction-to-case resistance to extend

power range of applications.
