LM4140BCM-1.2/NOPB

Voltage Reference Overview

The LM4140BCM-1.2/NOPB is a micropower low-dropout series voltage reference manufactured by Texas Instruments, housed in an 8-pin SOIC package. It provides a fixed output voltage of 1.25 V with an initial accuracy of 0.1%. The device features a temperature coefficient of 6 ppm/°C and operates within a junction temperature range of 0°C to +70°C. Maximum input voltage is 5.6 V, with a maximum shunt current of 8 mA. Typical supply current is 230 µA, reducing to ≤1 µA in disable mode.

Voltage Reference Feature Summary

Provides high precision with 0.1% initial accuracy for stable reference applications
Features ultra-low noise characteristics to minimize signal interference
Includes an enable pin for power management and extended battery life

Voltage Reference Applications

High-precision instrumentation circuits
Portable battery-powered test equipment
