NCP5208 Datasheet | onsemi

features include soft- start, source/sink current limits and thermal shutdown. Open- drain VTT OK output (POK) is added for system monitoring. The shutdown pin can tri- state the regulator output for Suspend To RAM (STR) state. This device is available in a SOIC- 8 package. Features http://onsemi.
