LM2597HVM-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2597HVM-5.0/NOPB is a step-down switching voltage regulator from the SIMPLE SWITCHER family, manufactured by Texas Instruments. It operates with a fixed 150 kHz internal oscillator and delivers up to 500 mA output current at a regulated 5 V. The device accepts an input voltage range of 4.5 V to 60 V. It features a shutdown mode that reduces quiescent current to 5 mA. The component is housed in an SOIC-8 surface-mount package and supports operation across a temperature range of -40°C to +125°C.
