LT1076IR#TRPBF

Voltage Regulators - DC DC Switching Regulators Overview

The LT1076IR#TRPBF is a monolithic bipolar switching regulator manufactured by Analog Devices Inc. It operates as a step-down (buck) converter with an adjustable output voltage range from 2.5 V to 35 V. The device supports a maximum switch current of 2 A and functions within an input voltage range of 8 V to 45 V. It integrates the power switch, oscillator, control circuitry, and current limit components on a single chip. The unit utilizes a TO-263-6 (D2PAK-5) surface-mount package and is rated for operation between -40°C and 85°C.
