0.8V Reference Ultra Low Dropout (0.2V@5A) Linear RegulatorThe 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 voltage
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 currentlimit
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 is enabled by
other power system. Pulling and holding the EN pin below
0.3V shuts off the output.
The APL5912 is available in a SOP-8P package
