Teilenummer : DMS-78XXSR
Function : 3.3V/5V/12V Outputs High-Effi ciency Switching Regulators with LM78XX Pinouts
Hersteller : Murata Power Solutions
Murata Power Solutions’ 7805SR-C (5V output), 7812SR-C (12V output) and 7803SR-C (3.3V output) step-down switching regulators are modern drop-in replacements for older, ineffi cient, LM7805 and LM7812 linear regulators.
The 78XXSR’s are pin- and size-compatible with industry-standard TO-220 SIP packages. A 260kHz switching frequency provides for effi ciencies as high as 95%. Full-load (up to 0.5A) operation from 9V, 12V, 24V, or 36V supplies at ambient temperatures up to +70°C requires no heat sinks, no temperature derating, no forced-air cooling, and no external capacitors.
