TYPICAL APPLICATION

The APE8981 series is a 3A ultra low dropout linea

regulator. This product is specifically designed to provide

well supply voltage for front-side-bus termination on

motherboards 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 powe

dissipation and provide extremely low dropout. The

APE8981 series integrates many functions. A Power-On-

Reset (POR) circuit monitors both supply voltages to

prevent wrong operations. A thermal shutdown and current

limit 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 othe

converter for power sequence.

The APE8981 series can be enabled by other powe

system. Pulling and holding the EN pin below 0.4V shuts of

the output.

The APE8981 series is available in DFN 3x3-10L &

ESOP-8 package which features small size as SO-8 and an

Exposed Pad to reduce the junction-to-case resistance.
