FN9219.5

Dual LDO with Low Noise, Low IQ and
High PSRR

ISL9011 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 LDO’s
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.
