LM4041BICT-1.2

Overview

The LM4041BICT-1.2 is a micropower shunt voltage reference manufactured by STMicroelectronics, providing a fixed typical output voltage of 1.225 V. It features an initial accuracy of ±0.5% at 25 °C and operates with an ultra-low current of 50 µA at 25 °C. The device exhibits a maximum temperature coefficient of 100 ppm/°C and supports a cathode current up to 12 mA. It functions within an extended temperature range of -40 °C to +125 °C and utilizes a SOT-23-3 surface mount package.

Feature Summary

• Provides stable 1.225 V output with high precision
• Ultra-low operating current for power restricted designs
• Stable operation with capacitive loads without external components

Applications

• Space-saving electronic designs
• Power restricted circuit applications
• Industrial and extended temperature environment systems

Procurement Notes

Verify the specific suffix ICT against official STMicroelectronics documentation to confirm the exact tolerance grade and package variant. Ensure compatibility with the required temperature range and load conditions before procurement. Cross-reference ordering codes with manufacturer datasheets to avoid discrepancies in electrical specifications or packaging types.

Selection Notes

Select this component when a fixed 1.225 V reference with ±0.5% accuracy is required in a compact SOT-23-3 package. It is suitable for designs prioritizing low quiescent current and stability under varying capacitive loads. Consider the 100 ppm/°C temperature coefficient for applications requiring moderate thermal stability across the -40 °C to +125 °C range.
