ISL9007

DATASHEET

ISL9007 is a high performance LDO that delivers a continuous

400mA of load current. It has a low standby current and

high PSRR and is stable with output capacitance of 1µF to

10µF with an ESR of up to 200m

.

The ISL9007 has a very high PSRR of 75dB and output noise

current of 50µA (typical), and 1µA (max) shutdown current, the

ISL9007 is an ideal choice for portable wireless equipment.

The ISL9007 comes in fixed voltage options of 3.3V, 2.85V,

2.8V, and 2.5V with ±1.8% output voltage accuracy

over-temperature, line and load. Other output voltage options

may be available upon request.

Features
