www.DataSheet4U.com February 2006 LM25007 42V, 0.5A Step-Down Switching Regulator LM25007 42V, 0.5A Step-Down Switching Regulator General Description The LM25007 is a monolithic step-down switching regulator featuring all of the functions needed to implement a low cost, efficient, power supply. Capable of driving a 0.5Amp load over a 9V-42V input voltage range, this device is easy to apply and is provided in the small MSOP-8 and the thermally enhanced LLP-8 packages. Ultra-fast transient response is achieved through the use of a constant on-time architecture with Vin feed forward. This feature provides an almost constant operating frequency over load and input voltage variations. The operating frequency can be adjusted with a single resistor.
