LM4121AIM5-ADJ/NOPB TI Voltage Reference | SOT-23-5 | 1.2V-5V, 0.5% Accuracy

Product Overview

The LM4121AIM5-ADJ/NOPB is a precision micropower, low dropout voltage reference from Texas Instruments. It offers an adjustable output voltage from 1.2V to 5V with an initial accuracy of 0.5% and a temperature coefficient of 50 ppm/°C (max). The device operates with a supply voltage as low as 1.8V and consumes only 160 µA (typical) of quiescent current, making it ideal for battery-powered applications. Housed in a compact SOT-23-5 package, it provides a stable and accurate reference for various precision circuits.
