Dual LDO with Low Noise, Very High
PSRR and Low IQ
Features
• Integrates Two 100mA High Performance LDO’s
ISL9000AMRNCP is a high performance dual LDO capable
of sourcing 100mA 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 200mΩ.
• IOUT per Channel is 50mA at TJ = +150°C
• Excellent Transient Response to Large Current Steps
• ±1.8% Accuracy Over all Operating Conditions
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.
• Excellent Load Regulation:
< 0.1% Voltage Change Across Full Range of Load
Current
• Low Output Noise: Typically 30µVrms @ 100µA (1.5V)
• Very High PSRR: 90dB @ 1kHz
• 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
individual LDO output. When both enable pins are low, the
device is in shutdown, typically drawing less than 0.1µA.
• Wide Input Voltage Capability: 2.3V to 5.5V
• Low Dropout Voltage: Typically 200mV @ 100mA
• 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
Surge During Enable
Device Information
The specifications for an Enhanced Product (EP) device are
defined in a Vendor Item Drawing (VID), which is controlled
by the Defense Supply Center in Columbus (DSCC).
“Hot-links” to the applicable VID and other supporting
application information are provided on our website.
