LM4050CIM3-10/NOPB

Voltage Reference Overview

The LM4050CIM3-10/NOPB is a precision micropower shunt voltage reference from Texas Instruments, housed in a compact SOT-23-3 surface-mount package. It provides a fixed output voltage of 10V with an initial accuracy of ±1%. The device operates within a temperature range of -40°C to +85°C and features a low temperature coefficient of 75 ppm/°C. Designed for high efficiency, it draws a cathode current as low as 100 µA while maintaining stable regulation up to a maximum cathode current of 15 mA.

Voltage Reference Feature Summary

• Provides a stable 10V reference voltage with ±1% initial accuracy
