¡¡¡¡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 1?F to 10?F 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 47?A 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 0.3?A. The ISL78302A is AEC-Q100 qualified. The ISL78302A is rated for the automotive temperature range £¨-40¡ãC to +105¡ãC£©.
