LM4040CIX3-2.1

Overview

The LM4040CIX3-2.1 is a micropower shunt voltage reference manufactured by Maxim Integrated, an Analog Devices Inc. brand. It provides a fixed output voltage of 2.048 V with an initial accuracy of 0.5%. The device operates within a temperature range of -40°C to +85°C and features a maximum temperature coefficient of 100 ppm/°C. Packaged in the ultra-small SC-70 (SOT-323) form factor, it is designed for space-constrained applications requiring stable voltage regulation.

Feature Summary

Provides a precise 2.048 V fixed output voltage suitable for calibration and measurement circuits.
Operates with ultra-low quiescent current to extend battery life in portable devices.
Maintains stability under capacitive loads without oscillation.
Utilizes a compact SC-70 package to minimize printed circuit board area.

Applications

Portable instrumentation and handheld meters
Battery-powered data acquisition systems
Medical equipment requiring stable reference voltages
Industrial process control sensors

Procurement Notes

Verify the manufacturer designation on the component marking, as Maxim Integrated products are now part of Analog Devices Inc. Ensure the suffix matches the specific package type and tolerance requirements for your design. Confirm RoHS compliance status through official documentation before procurement.

Selection Notes

Select this component when a low-cost, high-accuracy reference is needed in a small footprint. Compare against the LM4040AIM3X series if tighter initial accuracy or lower temperature coefficients are required. Verify that the operating current range meets the minimum load requirements of your specific application circuit.

Part Context

This component belongs to the LM4040 family of precision shunt voltage references. The family offers various fixed output voltages including 2.048 V, 2.5 V, 3.0 V, 4.096 V, and 5.0 V. Different suffixes indicate variations in accuracy grades, package types, and temperature ranges within the same functional architecture.

Replacement Considerations

LM4040CIZ-2.0/NOPB: Texas Instruments equivalent in TO-92 package. LM4040CIM3-2.0/NOPB: Texas Instruments equivalent in SOT-23-3 package. Verify pinout compatibility and thermal characteristics when substituting across manufacturers.
