DATASHEET ISL9001A FN6433 Rev 3.00 LDO with Low ISUPPLY, High PSRR December 10, 2015 ISL9001A is a high performance Low Dropout linear Features regulator capable of sourcing 300mA current. It has a low 300mA high performance LDO standby current and high-PSRR and is stable with output capacitance of 1F to 10F with ESR of up to 200m . Excellent transient response to large current steps Excellent load regulation: <0.1% voltage change across The ISL9001A has a very high PSRR of 90dB and output full range of load current noise less than 30V . A reference bypass pin allows RMS connection of a noise-filtering capacitor for low-noise and High PSRR: 90dB 1kHz high-PSRR applications. When coupled with a no load Wide input voltage capability: 2.3V to 6.5V quiescent current of 25A (typical), and 0.1A shutdown current, the ISL9001A is an ideal choice for portable wireless Extremely low quiescent current: 25A equipment. Low dropout voltage: typically 200mV 300mA The ISL9001A provides a P signal with delay time GOOD Low output noise: typically 30V 100A (1.5V) RMS programmable through an external capacitor. Stable with 1F to 10F ceramic capacitors Several different fixed voltage outputs are standard. Output Soft-start to limit input current surge during enable voltage options for each LDO range from 1.5V to 3.3V. Other output voltage options may be available upon request.
