ISL9012
Dual LDO with Low Noise, Low I
Q
, and
High PSRR
ISL9012 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 1
μ
F to 10
μ
F
with ESR of up to 200m
Ω
.
The device integrates a Power-On-Reset (POR) function for
the VO2 output. The POR delay for VO2 can be externally
programmed by connecting a timing capacitor to the CPOR
pin. 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 45
μ
A 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 0.1
μ
A.
Several combinations of voltage outputs are standard.
Others are available on request. Output voltage options for
each LDO range from 1.2V to 3.6V.
