DC1388A Quick Start Guide for LT3008 3μA Quiescent Current 20mA Linear Regulator
Quick start guide for the DC1388A demo circuit featuring the LT3008 LDO regulator, supporting 2V to 45V input and 20mA output with 3μA quiescent current.
Overview
The DC1388A demonstration circuit evaluates the LT3008, an ultralow quiescent current and low dropout (LDO) linear regulator. The circuit handles input voltages from 2V to 45V and provides up to 20mA of output current. With a quiescent current of only 3μA, the design is optimized for low-power and battery-operated applications. The board includes selectable jumpers for standard output voltages of 1.2V, 1.5V, 1.8V, 2.0V, 2.5V, 3.3V, and 5.0V, plus a user-configurable option for custom voltage settings using an external resistor. The document provides performance specifications, hardware setup instructions, and measurement procedures.
