描述
ISL9003A is a high performance single low noise, high PSRR LDO that delivers a continuous 150mA of load current. It has a low standby current and is stable with 1µF of MLCC output capacitance with an ESR of up to 200mΩ. The ISL9003A has a very high PSRR of 90dB and output noise is 20µVRMS (typical). When coupled with a no load quiescent current of 31µA (typical), and 0. 5µA shutdown current, the ISL9003A is an ideal choice for portable wireless equipment. The ISL9003A comes in many fixed voltage options with ±1. 8% output voltage accuracy over temperature, line and load. Other output voltage options are available on request.
