ISL9008AIRUFZ-T集成電路（IC）的線性+開(kāi)關(guān)穩(wěn)壓器規(guī)格書(shū)PDF中文資料

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 200m?.

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

less than 45μVRMS. When coupled with a no load quiescent

current of 46μA (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 may be available upon

request.
