LM2831XSD

Voltage Regulators - DC DC Switching Regulators Overview

The LM2831XSD is a high-frequency synchronous step-down DC-DC regulator manufactured by Texas Instruments. It operates with an input voltage range of 3 V to 5.5 V and provides an adjustable output voltage from 0.6 V to 4.5 V. The device delivers a maximum output current of 1.5 A. It features a fixed switching frequency of 1.6 MHz, enabling the use of small external components. The regulator is housed in a space-saving 6-pin WSON package with an exposed pad for thermal dissipation.
