ISL9000

Dual LDO with Low Noise, Very High PSRR and Low IQ

DATASHEET

ISL9000 is a high performance dual LDO capable of

sourcing 300mA current from each output. It has a low

standby current and very high PSRR and is stable with

output capacitance of 1µF to 10µF with ESR of up to 200m

.

The device integrates an individual Power-On-Reset (POR)

function for each output. The POR delay for VO2 can be

externally programmed by connecting a timing capacitor to

the CPOR pin. The POR delay for VO1 is internally fixed at

approximately 2ms. A reference bypass pin is also provided

for connecting a noise filtering capacitor for low noise and

high-PSRR applications.

The quiescent current is typically only 42µA 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 are from 1.5V to

3.3V. Other output voltage options may be available upon

request.
