Description

ISL9005 is a high performance Low Dropout linear regulator capable of sourcing 300mA current. It has a low standby current and high-PSRR and is stable with output capacitance of 1F to 10F with ESR of up to 200m. The ISL9005 has a high PSRR of 75dB and output noise less than 45VRMS. When coupled with a no load quiescent current of 50A (typical), and 0.1A shutdown current, the ISL9005 is an ideal choice for portable wireless equipment. Several different fixed voltage outputs are standard. Output voltage options for each LDO range are from 1.5V to 3.3V. Other output voltage options may be available upon request.
