APL5962A 0.8V Reference Ultra Low Dropout (0.2V@5A) Linear Regulator The APL5912 is a 5A ultra low dropout linear regulator. This product is specifically designed to provide well supply voltage for front-side-bus termination on motherboard and NB applications. The IC needs two supply voltages, a control voltage for the circuitry and a main supply volatege for power conversion, to reduce power dissipation and provide extremely low dropout. The APL5912 integrates many functions. A Power-On- Reset (POR) circuit monitors both supply voltages to prevent wrong operations. A thermal shutdown and current limit functions protect the device against thermal and current over-loads. A POK indicates the output status with time delay which is set internally. It can control other converter for power sequence. The APL5912 can be enabled by other power system. Pulling and holding the EN pin below 0.3V shuts off the output. The APL5912 is available in SOP-8-P package which features small size as SOP-8 and an Exposed Pad to reduce the junction-to-case resistance, being applicable in 2~3W applications.
