General Description
The APL5910 is a 1A 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 APL5910 integrates many functions. A Power-OnReset (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. The APL5910 can be enabled by other power systems. Pulling and holding the EN voltage below 0.4V shuts off the output. The APL5910 is available in a S……
