Low Noise LDO with Low IQ, High PSRR

ISL9008A 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.

Features

? High performance LDO with 150mA continuous output

? Excellent transient response to large current steps

? Excellent load regulation: <0.1 voltage change across full range of load current

? High PSRR: 65dB @ 1kHz

? Wide input voltage capability: 2.3V to 6.5V

? Very low quiescent current: 46μA
