LM4050AEX3-3.3/V+T

Voltage Reference Overview

The LM4050AEX3-3.3/V+T is a precision micropower shunt voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed reverse breakdown voltage of 3.3V with an initial accuracy of 0.1% and a maximum temperature coefficient of 50ppm/°C. The device operates within a wide current range from 60µA to 15mA and features low dynamic impedance. It is housed in a subminiature 3-pin SC70 surface-mount package (1.8mm x 1.8mm). The specifications are guaranteed over an operating temperature range of -40°C to +125°C, and the component is AEC-Q100 qualified.

Voltage Reference Feature Summary

Ultra-small 3-pin SC70 surface-mount package for space-critical applications
High initial accuracy of 0.1% ensured by laser-trimmed resistors
Stable operation without requiring external stabilizing capacitors
Capable of tolerating any capacitive load directly

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify that the specific /V suffix confirms AEC-Q100 automotive qualification status as indicated in the ordering information. Confirm the SC70 package code matches the required footprint dimensions. Ensure the 0.1% accuracy grade aligns with circuit tolerance requirements before finalizing procurement.

Voltage Reference Selection Notes

Select this component when high precision and compact size are required for shunt regulation. The 3.3V output suits standard logic levels. Verify that the minimum operating current of 60µA is maintained during all load conditions. Consider thermal derating if ambient temperatures approach the upper limit of the specified range.

Voltage Reference Part Context

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