ISL78302A is a high-performance dual LDO capable of sourcing 300mA 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 47µA with both LDOs 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. 3µA. The ISL78302A is AEC-Q100 qualified. The ISL78302A is rated for the automotive temperature range (-40°C to +105°C).
