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 (VCNTL) for the control circuitry, the other is a main supply Voltage(VIN) for power conversion, to reduce power dissipation and provide extremely low dropout voltage.

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