LDO

® ISL9001A Data Sheet January 18, 2007 FN6433.0 LDO with Low ISUPPLY, High PSRR ISL9001A 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 1μF to 10μF with ESR of up to 200mΩ. The ISL9001A has a very high PSRR of 90dB and output noise less than 30μVRMS. A reference bypass pin allows connection of a noise-filtering capacitor for low-noise and high-PSRR applications. When coupled with a no load quiescent current of 25μA (typical), and 0.1μA shutdown current, the ISL9001A is an ideal choice for portable wireless equipment. The ISL9001A provides a PGOOD signal with delay time programmable through an external capacitor. Several different fixed voltage outputs are standard. Other output voltage options for the LDO are available on request and range from 1.3V to 3.6V.
