LM4050AEM3-5.0/S7002735

Voltage Reference Overview

The LM4050AEM3-5.0 is a precision micropower shunt voltage reference manufactured by Texas Instruments, providing a fixed output of 5.0 V. It features an initial accuracy of ±0.1% and a temperature coefficient of 50 ppm/°C guaranteed over the -40°C to +125°C operating range. The device operates within a wide current range from 60 µA to 15 mA with low dynamic impedance. Packaged in a compact SOT-23-3 surface-mount format, it requires no external stabilizing capacitor for stability.

Voltage Reference Feature Summary

• Provides stable reference voltage without requiring external capacitors
• Maintains high precision across wide temperature variations
• Operates efficiently at very low quiescent currents

Voltage Reference Applications

• Analog-to-digital converter (ADC) reference inputs
• Digital-to-analog converter (DAC) voltage standards
• Precision measurement instrumentation circuits

Voltage Reference Procurement Notes

Verify the specific suffix against official documentation as standard distributors may list variants like LM4050AEM3X-5.0/NOPB. Confirm RoHS compliance status and ensure the package matches the required footprint. Check for discontinuation notices or process change notifications prior to final design approval.

Voltage Reference Selection Notes

Select this component when a 5.0 V reference with 0.1% accuracy is required in a small SOT-23 package. Ensure the circuit can maintain cathode current above 60 µA for regulation. Consider thermal management if operating near the upper temperature limit.

Voltage Reference Part Context

This part belongs to the LM4050 series of micropower shunt references. It shares core specifications with other voltage options in the family but is specifically tuned for a 5.0 V output. The A-grade designation indicates tighter initial accuracy tolerances compared to lower grades.

Voltage Reference Replacement Considerations

LM4050AEM3X-5.0/NOPB is a documented equivalent variant within the same product line offering identical electrical characteristics and pinout compatibility.
