SIT14503 provides fixed output of 5V. In addition, the product family is available with fixed outputs of 2.5V, 3.3V and 15V, or adjustable outputs from 0.65V to 24V (1), providing load currents up to 300m A. The quiescent current of the SIT14503 series is less than 1µA when disabled and less than 6µA at light loads. The power-good delay can be adjusted by external ponents, allowing the delay time to be configured to fit application-specific systems. It can be applied to the power management of automotive electronics, industrial control system and wide voltage battery power supply system. NOTE (1): If you need any other versions of the SIT14503 series except for the fixed 5V output, please contact the sales.
