Advanced Power Electronics Corp. APE8961 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 Pb-Free Package.
