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.
