ISL9014

Dual LDO with Low Noise, Low IQ and High PSRR

DATASHEET

ISL9014 is a high performance dual LDO capable of

sourcing 300mA current from both outputs. 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 200m

.

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.
