LM4050CIM3-3.0-T

Voltage Reference Overview

The LM4050CIM3-3.0-T is a precision micropower shunt voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 3.0V with an initial accuracy of ±0.1%. The device features a maximum temperature coefficient of 50ppm/°C and operates within a wide temperature range of -40°C to +125°C. Packaged in the ultra-small SC-70 (SOT-323) surface-mount format, it supports a shunt current range from 65µA to 15mA without requiring external stabilizing capacitors.

Voltage Reference Feature Summary

• Ultra-small 3-pin SC-70 package for space-critical applications
• High initial accuracy of ±0.1% ensured by laser-trimmed resistors
• Stable operation across wide operating currents without external capacitors

Voltage Reference Applications

• Portable instrumentation circuits
• Battery-powered measurement systems
• Data acquisition systems requiring stable references

Voltage Reference Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm the manufacturer designation as Analog Devices Inc./Maxim Integrated on official documentation. Ensure the component meets RoHS compliance standards required for your assembly process. Cross-reference the exact part number against current distributor catalogs to confirm availability status.

Voltage Reference Selection Notes

Select this component for designs prioritizing minimal footprint alongside high precision. The ±0.1% accuracy suits applications demanding tight tolerance. The 50ppm/°C temperature coefficient ensures stability across industrial temperature ranges. Verify that the 3.0V output aligns with system requirements before integration.

Voltage Reference Part Context

This component belongs to the LM4050/LM4051 family of two-terminal shunt voltage references. The series offers multiple reverse breakdown voltages including 1.225V, 2.048V, 2.500V, 3.000V, 3.3V, 4.096V, and 5.000V.
