SC1532 Description
Intended for applications such as Power Managed PCI, the SC1532 is designed to maintain a glitch-free 3.3V output when at least one of two inputs, 5V (VIN1) and 3.3V (VIN2), is present. The SC1532 bines a 5V to 3.3V linear regulator with an integral 3.3V bypass switch, along with logic and detection circuitry to control which supply provides the power for the output. Whenever VIN1 exceeds a predetermined threshold...
