The LP3995-50X3F is a Low Dropout Regulator (LDO) made by LOWPOWER. This device is a 3-terminal, monolithic, micro-package device with SOT89-3 RoHS plastic encapsulation. It is a voltage regulator providing up to 500mA output with high input voltage selector and current limiting features. It has a low dropout voltage of 150mV at maximum load current and a very low quiescent current of typically 75µA. It also features high input voltage tolerance and line regulation, low output noise and ripple, and stable output at light load currents. It also features a low current shutdown mode to reduce quiescent current to less than 0.1µA. The LP3995-50X3F is a high performance, cost-effective device designed for use in a wide range of consumer, industrial, automotive, and medical applications.
