LM4041CYM3-1.2-TR

Voltage Reference Overview

The LM4041CYM3-1.2-TR is a micropower shunt voltage reference manufactured by Microchip Technology, housed in a 3-pin SOT-23 surface-mount package. It provides a fixed reverse-breakdown output voltage of 1.225 V with an initial accuracy tolerance of ±0.5% at 25 °C. The device operates within a temperature range of -40 °C to +85 °C and features a maximum average temperature coefficient of 100 ppm/°C. Minimum operating current is specified at 60 µA, while the maximum operating current is limited to 12 mA.

Voltage Reference Feature Summary

Bandgap reference design incorporating temperature drift curvature correction for stable performance across varying temperatures and currents.
Advanced architecture that eliminates the requirement for external stabilizing capacitors while maintaining stability under capacitive loads.
Low dynamic impedance characteristic ensuring consistent reverse-breakdown voltage accuracy throughout the operational current range.

Voltage Reference Applications

Battery-powered equipment
Data acquisition systems
Instrumentation
Process control
Precision audio components

Voltage Reference Procurement Notes

Verify the specific C-grade designation corresponds to the required ±0.5% initial accuracy tolerance. Confirm the SOT-23 package type matches the target PCB footprint. Ensure the operating environment remains within the specified -40 °C to +85 °C industrial temperature range. Validate that the series resistor selection keeps the cathode current below the 12 mA maximum limit during peak supply conditions.

Voltage Reference Selection Notes

Select this component when a fixed 1.225 V reference is needed in space-constrained designs utilizing SOT-23 packaging. The low minimum operating current of 60 µA makes it suitable for power-restricted applications. Verify that the load regulation requirements align with the specified voltage change characteristics over the operating current range from 60 µA to 12 mA.

Voltage Reference Part Context

This part belongs to the LM4041 family of precision micropower shunt voltage references produced by Microchip Technology. The LM4041 series complements the LM4040 family, which offers higher voltage options such as 2.5 V, 4.096 V, and 5.0 V. Both families share similar architectural benefits, including small package sizes and high stability without external capacitors.
