ISL9008A

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 1

μF of

MLCC output capacitance with an ESR of up to 200m

Ω.

The ISL9008A has a high PSRR of 65dB and output noise

less than 45

current of 46

μA (typical), and 0.5μA shutdown current, the

ISL9008A is an ideal choice for portable wireless equipment.

The ISL9008A comes in several fixed voltage options with

±1.8% output voltage accuracy over temperature, line and

load. Other output voltage options are available on request.
