LM4051CIM3-1.2

Voltage Reference Overview

The LM4051CIM3-1.2 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 0.5%. The device operates within a temperature range of -40°C to +85°C and features a maximum temperature coefficient of 50 ppm/°C. It supports a shunt current range from 60µA to 15mA and utilizes a 3-pin SC-70 surface-mount package.

Voltage Reference Feature Summary

Ultra-small 3-pin SC-70 surface-mount package designed for space-critical applications
No external stabilizing capacitor required while ensuring stability with any capacitive loads
Laser-trimmed resistors ensure excellent initial accuracy across the operating temperature range

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify that the ordering suffix matches the specific grade and package variant required. Confirm the manufacturer designation as Analog Devices Inc. or Maxim Integrated depending on the supply chain source. Ensure the part number corresponds to the fixed 1.225V output version rather than adjustable or other voltage variants.

Voltage Reference Selection Notes

Select this component when a compact footprint is critical alongside high precision. The 0.5% initial accuracy and 50 ppm/°C temperature coefficient suit applications requiring stable references in limited spaces. Verify that the 60µA minimum operating current aligns with the system's power budget constraints.
