The LM2596HVS-ADJRG is a high-performance DC-DC step-down buck switching voltage regulator designed to deliver up to 3A output current with excellent line and load regulation. This IC is part of the LM2596 series, optimized for simplicity, efficiency, and reliability, making it one of the most widely used regulators in Bangladesh for industrial, commercial, and consumer electronics projects.

It is available in fixed output versions (3.3V, 5V, 12V) and an adjustable output version with a wide voltage range from 1.2V to 37V, providing flexibility for different circuit requirements. With its high input voltage capability (up to 40V), the LM2596HV-ADJRG is ideal for power supplies, battery chargers, automotive electronics, LED drivers, embedded systems, and Arduino or ESP32 based projects.

Engineered with a 150 kHz fixed-frequency internal oscillator, the regulator ensures stable switching and reduced external components, making PCB design simple. Its built-in thermal shutdown, current limit protection, and external shutdown capability provide robust safety features for long-term operation in demanding environments.

The LM2596HVS-ADJRG is highly efficient, with a typical efficiency above 80%, which reduces heat dissipation and power loss. It only requires four external components, significantly simplifying the design of compact, high-efficiency switching power supplies.
