Switching Regulators operate over -40 to +70°C range.October 12, 2007 -
Series 78SR regulators suit applications requiring 3.3 or 5 V outputs, at 2 A or less, from 8-32 V inputs. At nominal 12 V input, full-load efficiencies are 95% for 5 V models, and 93% for 3.3 V models. Available in choice of rugged 3-pin SIP packages, they offer 8-32 Vdc input voltage range with ±0.35% line regulation.

78SR Step-Down Switching Regulators Provide High-Efficiency Drop-in Replacement for LM7805 & LM7812 Applications
Murata Power Solutions (formerly known as C&D's Power Electronic division) new 78SR Series 2A switching regulators provide high operating efficiency for applications requiring 3.3V or 5V outputs, at 2 Amps or less, from 8 to 32V inputs. At a nominal 12V input, full-load efficiencies are typically 95% for 5V models, and 93% for 3.3V models.
Features
Up to 95% efficiency at full load without costly heat sinks or fans.
3.3V/2A & 5V/2A outputs are pin-compatible with 1.5A 78xx modules.
Wide 8 to 32Vdc input voltage range with ±0.35% line regulation.
-40 to +70°C full load operation at 24V inputs with no thermal derating.
Why would I specify the 78SR?
Unlike alternative products which typically suffer significant efficiency drops at low load currents, 78SR switching regulators operating at 12Vin and 25% load (0.5A) deliver efficiencies of 90% for 5V models, and 87% for 3.3V models.
What are the benefits of the PRODUCT?
Choice of rugged 3-pin SIP packages.
No thermal derating with 12 or 24V inputs.
Enhanced performance.
Numerous applications.
