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 1F to 10F with ESR of up to 200m. 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 42A 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 0.1A. Output voltage for the LDO are VOUT1 = 3.3V and VOUT2 = 1.8V.
