High Performance Regulated Charge Pump

General Description

The LP3120 is a high performance charge pump DC/DC converter that produces a regulated 5V output. No external inductor is required for operation. The operating voltage range is 2.8V to V OUT . Internal soft-start circuitry effectively reduces the in-rush current both while start-up and mode change. The LP3120 features very low quiescent current, over current protection and short circuit protection. The LP3120 is available in SOT23-6 package.
