LM4041DIM3-1.2 TI Precision Micropower Shunt Voltage Reference | SOT-23-3 | 1.225V Output, ±0.5% Accuracy

Product Overview

The LM4041DIM3-1.2 from Texas Instruments is a precision micropower shunt voltage reference designed for space-constrained applications. Housed in a compact SOT-23-3 package, it provides a fixed 1.225V output with an initial accuracy of ±0.5% (D grade). Operating over a wide current range from 60 µA to 12 mA, it offers excellent temperature stability (100 ppm/°C typical) and low dynamic impedance, making it ideal for portable and battery-powered systems. The device requires no external capacitor for stability and is fully specified over the industrial temperature range of -40°C to +85°C.
