ISL9003A Description
ISL9003A Low Noise LDO with Low IQ and High PSRR 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 200m. The ISL9003A has a very high PSRR of 90dB and output noise is 20µVRMS (typical).
