APE8963  
3A ULTRA LOW DROPOUT LINEAR REGULATOR  
FEATURES  
DESCRIPTION  
The APE8963 is a 3A ultra low dropout linear 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 power dissipation and provide  
extremely low dropout. The APE8963 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 other converter for power sequence. The APE8963  
can be enabled by other power system. Pulling and holding  
the EN pin below 0.3V shuts off the output.

ESOP-8 & TDFN 3x3-10L Pb-Free & Halogen-Free  
Package.  
The APE8963 is available in ESOP-8 and TDFN 3x3-  
10L packages which features small size as an Exposed Pad  
to reduce the junction-to-case resistance, being applicable  
in 2~3W applications.
