LM4050CIX3-5.0+T

Voltage Reference Overview

The LM4050CIX3-5.0+T is a precision two-terminal shunt-mode bandgap voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed reverse breakdown output voltage of 5.000V. The device utilizes BICMOS technology and is housed in an ultra-small 3-pin SC-70 surface-mount package measuring 1.80 x 1.80 mm. It operates within a temperature range of -40°C to +125°C, featuring a maximum temperature coefficient of 50ppm/°C and an initial accuracy of 0.5%. The component supports a wide operating current range from 60µA to 15mA with low dynamic impedance.

Voltage Reference Feature Summary

• Ultra-small 3-pin SC-70 surface-mount package for space-critical applications
• Precision two-terminal shunt-mode bandgap voltage reference topology
• No external stabilizing capacitor required while ensuring stability with capacitive loads

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify the specific suffix 'C' indicates the 0.5% accuracy grade rather than the standard 0.1% or 0.2% grades found in other variants. Confirm the '+T' designation corresponds to tape-and-reel packaging suitable for automated assembly. Ensure the manufacturer source is correctly identified as Analog Devices or Maxim Integrated, as legacy documentation may list National Semiconductor or Texas Instruments due to corporate acquisitions.

Voltage Reference Selection Notes

Select this component when a 5.000V reference is required in a minimal footprint environment. The 0.5% initial accuracy suits applications where tighter tolerances are not critical. Verify that the system design can accommodate the minimum 60µA cathode current to maintain regulation. Consider the 50ppm/°C temperature coefficient against the ambient thermal conditions of the final enclosure.

Voltage Reference Part Context

This part belongs to the LM4050/LM4051 family of micropower shunt 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. The devices are laser-trimmed to ensure excellent initial accuracy and are designed for high reliability in harsh environments.

Voltage Reference Replacement Considerations

LM4050CIX3-5.0 (without '+' or 'T' suffixes) represents the same electrical specifications but may differ in packaging format or environmental compliance status.
