Description

General part information

LM2594 Series

The LM2594xx series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving a 0.5-A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3 V, 5 V, 12 V, and an adjustable output version, and are packaged in a 8-pin PDIP and a 8-pin surface-mount SOIC package.

Requiring a minimum number of external components, these regulators are simple to use and feature internal frequency compensation, a fixed-frequency oscillator, and improved line and load regulation specifications.

The new product, LMR36506, offers reduced BOM cost, higher efficiency, and smaller solution size with many other features. See theDevice Comparison Tableto compare specs.Start WEBENCH DesignwithLMR36506.
