LM2596DP-3.3

Voltage Regulators - DC DC Switching Regulators Overview

The LM2596DP-3.3 is a monolithic integrated circuit step-down switching regulator from the LM2596 series, manufactured by TAEJIN (HTC Korea). It provides a fixed 3.3V output and supports up to 3.0A load current with excellent line and load regulation. The device operates with an input voltage range of 4.5V to 40V and utilizes a fixed 150kHz internal oscillator. Designed for high efficiency, it requires only four external components. Key protection features include thermal shutdown and current limiting.
