ISL9007IUNZ集成電路（IC）的線性+開關(guān)穩(wěn)壓器規(guī)格書PDF中文資料

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 200mΩ.

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

less than 30μVRMS. When coupled with a no load quiescent

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.
