1A ULTRA LOW DROPOUT LINEAR REGULATOR
FEATURES
DESCRIPTION
The APE8961 is a low-dropout voltage regulator
suitable for various electronic equipments. It provides
constant voltage power source. The dropout voltage of
APE8961 is below 0.14V in full rated current (1A). This
regulator has various functions such as a peak current
protection, a thermal shut down, a short circuit protect.
The APE8961 is available in SO-8 and TO-220-5L
power packages which features small size to reduce the
junction-to-case resistance, being applicable in 0.5~3W
applications.
Ultra Low Dropout - 0.14V(Typical) at 1A
Output Current
Adjustable Mode: 1.22V Reference Voltage
Fixed Mode : 5V, 9V, 12V Output Voltage
Operating Voltage can be up to 23V.
Current-Limit and Thermal Shutdown Protection
Short Circuit Protection, Enable Function.
Built-in Internal SW P-channel MOS
SO-8, TO-220-5L and TO-220-5LR
