Advanced Power Electronics Corp. APE8962 2A ULTRA LOW DROPOUT LINEAR REGULATOR FEATURES DESCRIPTION The APE8962 is a low-dropout voltage regulator suitable for various electronic equipments. It provides constant voltage power source. The dropout voltage of APE8962 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. Ultra Low Dropout - 0.27V(Typical) at 2A Output Current Adjustable Mode: 1.22V Reference Voltage Fixed Mode: 5V, 9V, 12V Output Voltage Operating Voltage : up to 23V for TO-220-5L and TO-263-5L Packages. up to 16V for TO-252-5L and SO-8 Packages. Current-Limit and Thermal Shutdown Protection Short Circuit Protection, Enable Function. Built-in Internal SW P-channel MOS SO-8, TO-252-5L, TO-220-5L, TO-220-5LR and TO-263-5L Pb-Free Packages.
