The NCP5501DT50G is a linear fixed low-drop Voltage Regulator provides up to 500mA over a user-adjustable output range of 1.25 to 5V with typical output voltage accuracy better than 3%. An internal PNP pass transistor permits low dropout voltage and operation at full load current at the minimum input voltage. This regulator is ideal for applications that require a broad input voltage range and low dropout performance up to 500mA load using low cost ceramic capacitors. Integral protection features include short circuit current and thermal shutdown.
