LM2595SX-3.3/E5000295

Voltage Regulators - DC DC Switching Regulators Overview

The LM2595SX-3.3 is a SIMPLE SWITCHER power converter designed as a 1-A step-down voltage regulator. It operates with an input voltage range of 4.5 V to 40 V and provides a fixed 3.3 V output. The device integrates a 150 kHz switching frequency, enabling the use of compact external components. Packaged in a TO-263 (D2PAK) case, it supports surface-mount installation. The regulator features internal frequency compensation and current limiting for simplified design and robust performance across industrial temperature ranges.
