Switching regulators offer 96% efficiency

The 78SR Series 2-A switching regulators provide full-load efficiencies of 96% for 5-V models, and 93% for 3.3-V models. At 12 VIN and 25% load it delivers efficiencies of 90% for 5-V models and 87% for 3.3-V models. The regulators are available in a standard 0.09-in.2 vertical-mount SIP and a horizontal-mount version with a height of 0.30 in.

The series allows full-load operation from 9, 12, or 24 V, supplies at ambient temperatures up to +70°C without heat sinks, forced-air cooling, or temperature derating. Applications for the new regulators include battery-powered instruments, test equipment, automotive, marine and recreational vehicles. (From $13.95 each or $7 ea/large qty—available now.)
