Product Overview

The 7812SR-C is a 1-output high-efficiency Step-down Switching Regulator with LM78xx pinouts. 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. 78SR switching regulators provide many significant improvements over their linear counterparts such as lower quiescent current (3 vs. 5mA), higher input voltage (40 vs. 32V) and better output accuracy (±2 vs. ±5%). All these features combine to make 78SR regulators ideal for new or existing LM7805 and LM7812 applications requiring full-load operation at elevated voltages. However, this device will stay in regulation at lower input voltages if it is operated at less than its rated loads.
  • Not internally fused
  • Regulator's internal input and output circuits share a common connection
  • Does not provide input or output overvoltage protection
  • Designed to be hand soldered to PC-boards using no-clean solders
  • Ideal for powering instrumentation from 9/12/24/28V supplies or batteries
  • Can be used with unregulated DC supplies protection
  • Built-in filter capacitors - No external components required
  • Low quiescent current (3mA)
  • -40 to 70°C Operating temperature range at full load, short-circuit protection
