LM2596T-ADJ/LF02

Voltage Regulators - DC DC Switching Regulators Overview

The LM2596T-ADJ/LF02 is a SIMPLE SWITCHER power converter from Texas Instruments, functioning as a 150 kHz step-down voltage regulator. It supports an input voltage range of 4.5 V to 40 V and delivers up to 3 A output current. The adjustable version allows output voltages from 1.2 V to 37 V via external resistors. Operating in voltage-mode control, it features built-in thermal shutdown and current limiting. The device utilizes a TO-220-5 through-hole package for robust thermal performance.
