ISL9008A集成电路（IC）的线性+开关稳压器规格书PDF中文资料

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.
