SC1532 Overview
Key Specifications
Package: SOP
Length: 4.9 mm
Width: 3.9 mm
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.
Key Features
- Glitch-free transition between input sources
- Internal logic selects input source
- 5V detector with hysteresis
- 1% regulated output voltage accuracy
- 400mA load current capability APPLICATIONS
