General Description

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 voltage

for power conversion, to reduce power dissipation and provide extremely low dropout.
