LM2595S-12-TI

Voltage Regulators - DC DC Switching Regulators Overview

The LM2595S-12 is a SIMPLE SWITCHER step-down voltage regulator from Texas Instruments, operating at a fixed 150 kHz switching frequency. It provides a fixed 12 V output with a maximum load current of 1 A. The device accepts an input voltage range of 4.5 V to 40 V and features low quiescent current of 5 mA. It includes internal frequency compensation, a 150 kHz oscillator, and TTL shutdown capability. The regulator offers thermal shutdown and current limiting protection, housed in a TO-263-5 surface-mount package.
