Applications
The APL5916 is a 7A ultra low dropout linear regulator.
This product is specifically designed to provide well supply volatage for motherboards and VGA card applications.
The IC needs two supply voltages, a control voltage for the circuitry, and a main supply voltage for power conversion, to reduce power dissipation and provide extremely low dropout.
The APL5916 integrates many functions into a single package.
A Power-On-Reset (POR) circuit monitors both supply voltages to prevent wrong operations.
Thermal shutdown and current limit functions protect the device against thermal and current over-loads.
POK indicates that the output status with time delay which is set internally.
It can control other converter for power sequence.
The APL5916 can be enabled by other power system.
Pulling and holding the EN pin below 0.
3V shuts off the output.
The APL5916 is available in SOP-8P package which features small size as SOP-8 and an Exposed Pad to reduce the junction-to-case resistance, being applicable in 2~2.
6W applications.
