Description

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 1F to 10F with an ESR of up to 200m. The ISL9007 has a very high PSRR of 75dB and output noise less than 30VRMS. When coupled with a no load quiescent current of 50A (typical), and 1A (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.
