December 12, 2007 FN6620.0Data Sheet

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

Integrates Two 100m A High Performance LDO’s

ISL9000AMRNCP is a high performance dual LDO capable

IOUT per Channel is 50m A at TJ = +150°C

of sourcing 100m A current from each output. It has a low

standby current and very high PSRR and is stable with Excellent Transient Response to Large Current Steps

output capacitance of 1µF to 10µF with ESR of up to 200mΩ.

±1.8% Accuracy Over all Operating Conditions

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

Excellent Load Regulation:

function for each output. The POR delay for VO2 can be < 0.1% Voltage Change Across Full Range of Load externally programmed by connecting a timing capacitor to Current the CPOR pin. The POR delay for VO1 is internally fixed at

Low Output Noise: Typically 30µVrms @ 100µA (1.5V)

approximately 2ms. A reference bypass pin is also provided

for connecting a noise filtering capacitor for low noise and Very High PSRR: 90d B @ 1k Hz

high-PSRR applications.

Extremely Low Quiescent Current: 42µA (both LDOs active)

The quiescent current is typically only 42µA with both LDO’s enabled and active. Separate enable pins control each Wide Input Voltage Capability: 2.3V to 5.5V individual LDO output. When both enable pins are low, the

Low Dropout Voltage: Typically 200m V @ 100m A

device is in shutdown, typically drawing less than 0.1µA.

Stable with 1µF to 10µF Ceramic Capacitors

Output voltage for the LDO are VOUT1 = 3.3V and

VOUT2 1.8V. Separate Enable and POR Pins for Each LDO Soft-Start and Staged Turn-On to Limit Input Current
