Dual LDO with Low Noise, Low IQ, 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 1µF to
10µF with ESR of up to 200m.
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 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 are available on request.
