The BA033CC0WFP-E2: The BA033CC0WFP-: The ROHM BA033CC0WFP- is a single-output positive fixed LDO regulator delivering 3.3 V at up to 1 A. Its 55 dB PSRR at 120 Hz means it knocks down 50/60 Hz rectifier ripple by about 560×, so downstream analog or MCU rails see a clean DC bus. The 25 V input maximum gives headroom for unregulated supplies or 24 V industrial buses.
1 A continuous — load budget and thermal planning
Rated for 1 A output with a quiescent current of 2.5 mA (max 5 mA), the BA033CC0WFP- suits moderate-current rails. The TO-252-5 package has a tab for heatsinking. Enable pin lets you sequence the rail or shut it down for idle power savings.
Industrial temp range and protection suite
Built-in over-current, over-temperature, and over-voltage protection means it survives load dumps and shorted outputs without external crowbar circuitry — one fewer BOM line for protection.
