微源半导体 LP3211 SOT23-6 高性能稳压电荷泵
General Description
The LP3211 is a high performance charge pump DC/DC converter that produces a regulated 5V output. No external inductor is required for operation. Theoperating voltage range is 2.8V to VOUT. Internal soft-start circuitry effectively reduces the in-rush current both while start-up and mode change.
The LP3211 features very low quiescent current, over current protection and short circuit protection.
The LP3211 is available in SOT-23-6 package.
