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.
