RENESAS ISL9003AIEBZ-T

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 20μν RMS (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.
