LM4051AEM3-1.2+T

Voltage Reference Overview

The LM4051AEM3-1.2+T is a precision two-terminal shunt-mode bandgap voltage reference with a fixed reverse breakdown voltage of 1.225V. It features an initial accuracy of 0.1% and a maximum temperature coefficient of 50ppm/°C over the -40°C to +125°C range. The device operates within a shunt current range of 60µA to 15mA, utilizing laser-trimmed resistors for stability. It is housed in a 3-pin SOT23 surface-mount package.

Voltage Reference Feature Summary

Laser-trimmed resistors ensure excellent initial accuracy without requiring external stabilizing capacitors.
Maintains stability with any capacitive load while eliminating the need for output capacitors.
Provides stable reverse breakdown voltage accuracy across a wide operating current range.

Voltage Reference Applications

Portable, battery-powered equipment
Notebook computers
Cell phones
Industrial process controls

Voltage Reference Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and accuracy grade. Ensure the component matches the required electrical specifications for your design. Cross-reference the part number with the latest datasheet revision to confirm availability and compliance status.

Voltage Reference Selection Notes

Select this component when space constraints require a small surface-mount package alongside high precision requirements. The 0.1% initial accuracy makes it suitable for applications demanding tight voltage tolerances. Consider the 60µA minimum operating current for low-power designs.

Voltage Reference Part Context

This component belongs to the LM4050/LM4051 family of micropower shunt voltage references. The LM4051 variant specifically offers a 1.225V fixed output, distinguishing it from the LM4050 series which provides higher voltage options. Both share identical packaging and general performance characteristics.
