Overview

The DC1585A is a demonstration circuit for the LT3083, a 3A low dropout (LDO) linear regulator. It provides a platform for evaluating the regulator performance across an input range of 1.7V to 23V, featuring a single-resistor architecture that allows for easy voltage adjustment.

Why Choose This Part

The board demonstrates the LT3083 capability to provide high output current with minimal voltage drop. Its unique architecture allows for easy paralleling of multiple ICs for higher current and better heat distribution.

Applications

High Current Linear Regulation
Providing up to 3A of clean power for noise-sensitive analog circuits and high-speed digital rails.
Post-Switching Regulator
Filtering ripple and noise from switching power supplies to provide a stable, low-noise output.
Variable Voltage Lab Supply
Serving as a fundamental component in adjustable bench-top power supply prototypes.
Low Voltage Digital Rails
Generating precise low-voltage outputs for modern FPGAs and processors starting from 1.2V.

Getting Started

To use the DC1585A, connect a DC input voltage between 1.7V and 23V to the VIN and GND terminals. Ensure adequate thermal management if operating at high current or large voltage differentials, as the linear regulator dissipates heat proportional to the power drop.
