com 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 combines 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 value, the internal 3.
3V PMOS linear regulator is enabled, and the internal pass NMOS is turned off.
When VIN1 falls below a lower thr...
