A monolithic 1A step-down (buck) voltage regulator from National Semiconductor that is a high efficiency replacement for the more conventional 3-pin linear regulators. The device requires a minimum number of external components and is simple to use.

Its design substantially reduces the size of heatsink required and, in many cases, no thermal management is required as dissipated power is low.

04 October 2011 Question by: Rapid Customer | Product code: 82-0658
Q. Why are the TE-092-005 £10, whilst these switching regulators claim to do the same thing for a fraction of the price?
A. Hi Pete thank for your enquiry - unfortunately i can find no link to TE-092-005 - can you supply an order code for us to investigate
