DESCRIPTION
The APE8957 is a 7A ultra low dropout linear regulator.
The 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
voltage for the circuitry and a main supply voltage for power
conversion, to reduce power dissipation and provide
extremely low dropout. The APE8957 integrates many
functions. A Power-on-Reset(POR) circuit monitors both
supply voltage to prevent wrong operations. A thermal
shutdown and current limit functions protect the device
against thermal and current over-load. A POK indicates the
output status with time delay which is set internally. It can
control other converter for power sequence. The APE8957
can be enabled by other power system. Pulling and holding
the EN pin below 0.4V shuts off the output.
The APE8957 is available in ESOP-8 package which
features small size as SO-8 and exposed pad to reduce the
junction-to-case resistance, being applicable in 2~3W
applications.
