The APL5932A/B/C/D is a 3A ultra low dropout linear
regulator. The IC needs two supply voltages, one is a
control voltage (VCNTL) for the control circuitry, the other is
a main supply Voltage(VIN) for power conversion, to re-
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
VCNTL and VIN pins to prevent erroneous operations. The
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.
