Dual LDO with Low Noise, Low IQ, and High PSRR
Jump to Page Section:
Overview
Description
ISL9011A is a high performance dual LDO capable of sourcing 150mA current from Channel 1 and 300mA from Channel 2. The device has a low standby current and high-PSRR and is stable with output capacitance of 1µF to 10µF with ESR of up to 200mΩ. A reference bypass pin allows an external capacitor for adjusting a noise filter for low noise and high PSRR applications. The quiescent current is typically only 45µA with both LDOs enabled and active. Separate enable pins control each individual LDO output. When both enable pins are low, the device is in shutdown, typically drawing less than 0. 1µA. Several combinations of voltage outputs are standard. Output voltage options for each LDO range from 1. 5V to 3. 3V. Other output voltage options may be available upon request.
