DATASHEET ISL9000 FN9217 Rev 4.00 Dual LDO with Low Noise, Very High PSRR and Low IQ March 11, 2008 ISL9000 is a high performance dual LDO capable of Features sourcing 300mA current from each output. It has a low Integrates two 300mA high performance LDOs standby current and very high PSRR and is stable with output capacitance of 1F to 10F with ESR of up to 200m . 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 Excellent load regulation: externally programmed by connecting a timing capacitor to < 0.1% voltage change across full range of load current the CPOR pin. The POR delay for VO1 is internally fixed at Low output noise: typically 30V 100A (1.5V) RMS approximately 2ms. A reference bypass pin is also provided for connecting a noise filtering capacitor for low noise and Very high PSRR: 90dB 1kHz high-PSRR applications. Extremely low quiescent current: 42A (both LDOs active) The quiescent current is typically only 42A with both LDOs Wide input voltage capability: 2.3V to 6.5V enabled and active. Separate enable pins control each Low dropout voltage: typically 200mV 300mA individual LDO output. When both enable pins are low, the device is in shutdown, typically drawing less than 0.1A. Stable with 1F to 10F ceramic capacitors Several combinations of voltage outputs are standard. Separate enable and POR pins for each LDO Output voltage options for each LDO range are from 1.5V to Soft-start and staged turn-on to limit input current surge 3.3V. Other output voltage options may be available upon during enable request.
