LM2596TVADJG

Voltage Regulators - DC DC Switching Regulators Overview

The LM2596TVADJG is a monolithic integrated circuit designed for simple and convenient step-down switching regulator applications. It functions as an adjustable DC-DC buck converter capable of driving a load current up to 3.0 A with excellent line and load regulation. The device operates with an input voltage range from 4.5 V to 40 V, providing an adjustable output voltage between 1.23 V and 37 V. It features a fixed internal oscillator operating at a frequency of 150 kHz, which allows for the use of smaller external filter components compared to lower-frequency regulators. The component is housed in a TO-220-5 package.
