General Description
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.
