7805SRH-C

The 7805SRH-C is a 1-output Step-down Switching Regulator, modern drop-in replacements for older, inefficient, LM7805 and LM7812 linear regulators. A 260kHz switching frequency provides for efficiencies as high as 95%. Full-load (up to 0.5A) operation from 9, 12, 24 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. 7805SRH-C switching regulator provides many significant improvements over their linear counterparts - lower quiescent current (3mA vs. 5mA), higher input voltage (40V vs. 32V) and better output accuracy (±2% vs. ±5%). All these features combine to make 78SR regulator ideal for new or existing LM7805 and LM7812 applications requiring full-load operation at elevated voltages.

• Up to 95% efficiency - No heat sinks or thermal derating required
• Low quiescent current (3mA)
• Built-in filter capacitors - No external components required
• -40 to +70°C Operation at full load, short-circuit protection
• Excellent load (±0.2%) and line (±0.3%) regulation
• Ideal for powering instrumentation from 9/12/24/28V supplies or batteries
• Can be used with unregulated DC supplies protection
