APE8962
2A ULTRA LOW DROPOUT LINEAR REGULATOR
TYPICAL APPLICATION
1
The APE8962 is a low-dropout voltage regulator
suitable for various electronic equipments. It provides
constant voltage power source. The dropout voltage of
A
PE8962 is below 0.27V in full rated current (2A). This
regulator has various functions such as a peak current
protection, a thermal shut down, a short circuit protect.
The APE8962 is available in SO-8, TO-252-5L,
TO-220-5L and TO-263-5L power packages which features
small size to reduce the junction-to-case resistance,
being applicable in 0.5~3W applications.
