Dual LDO with Low Noise, Very High PSRR and Low IQ
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.
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 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.
Output voltage for the LDO are VOUT1 = 3.3V and
VOUT2 = 1.8V.
