LM4050CIX3-5.0+

Voltage Reference Overview

The LM4050CIX3-5.0+ is a precision two-terminal shunt voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed reverse breakdown output voltage of 5.0V with an initial accuracy of ±0.5%. The device utilizes BICMOS technology and is housed in a compact SC-70 (SOT-323) surface-mount package measuring 1.80 x 1.80 mm with three pins. It operates within a temperature range of -40°C to +125°C, featuring a maximum temperature coefficient of 50ppm/°C.

Voltage Reference Feature Summary

• Ultra-small 3-pin SC-70 surface-mount package for space-critical designs
• Laser-trimmed resistors ensure high initial accuracy without external calibration
• Capable of handling wide operating current ranges from microamps to milliamps
• Stable operation guaranteed over extended industrial temperature ranges

Voltage Reference Applications

• Portable battery-powered equipment requiring stable reference voltages
• Industrial process control systems needing precise analog references
• Automotive electronics applications demanding reliability across temperature extremes

Voltage Reference Procurement Notes

Verify the specific suffix 'C' corresponds to the required ±0.5% accuracy grade and 'I' indicates the industrial temperature range. Confirm the '+'' denotes lead-free compliance. Ensure the SC-70 footprint matches your PCB layout constraints before ordering.

Voltage Reference Selection Notes

Select this component when a fixed 5V reference is needed in a minimal footprint. The ±0.5% tolerance suits general-purpose applications where tighter precision is not critical. Consider the SC-70 package size relative to available board space compared to larger SOT-23 alternatives.

Voltage Reference Part Context

This part belongs to the LM4050 family of micropower shunt voltage references. The series offers multiple fixed voltage options including 1.225V, 2.048V, 2.5V, 3.0V, 3.3V, 4.096V, and 5.0V. The family is characterized by low dynamic impedance and stability without external capacitors.

Voltage Reference Replacement Considerations

LM4050CEX3-5.0+ is a direct equivalent offering identical electrical specifications but packaged in SOT-23 instead of SC-70. Verify pinout compatibility and physical dimensions if substituting between these package types.
