ISL78302AARMMZ-T General Description

ISL78302 is a high performance dual LDO capable of sourcing 300mA current from each output. It has a low standby current and is stable with an output capacitance of 1µF to 10µF and an ESR of up to 200mΩ.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 0.5µA.The part operates down to 2.3V and up to 6.5V input. The typical output voltage can be as low as 1.2V and as high as 3.3V for each regulator. Please refer to the “Ordering Information” on page 3 for standard options. The ISL78302 is AEC-Q100 qualified at the automotive temperature range of -40°C to +105°C.
