LM4051AIM3-1.2+

Voltage Reference Overview

The LM4051AIM3-1.2+ is a precision micropower shunt voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed reverse breakdown voltage of 1.225V with an initial accuracy of 0.1% at 25°C and a maximum temperature coefficient of 50ppm/°C. The device operates within a wide current range of 60µA to 15mA and features low output noise of 28µVRMS (10Hz to 10kHz). It is housed in an ultra-small 3-pin SC70 surface-mount package measuring 1.8mm x 1.8mm, designed for space-critical applications without requiring external stabilizing capacitors.
