ISL9007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.
