TS4041CILT-1.2

Overview

The TS4041CILT-1.2 is a micropower shunt voltage reference manufactured by STMicroelectronics, providing a stable 1.225V output. It operates within an industrial temperature range of -40°C to +85°C and features a maximum temperature coefficient of 150ppm/°C. The device supports a cathode current of up to 70 µA and delivers an output current of 12 mA. Initial accuracy at 25°C is specified at ±1%. Packaged in a surface-mount SOT-23-3 (TO-236-3) case, it is designed for space-constrained applications requiring low power consumption.

Feature Summary

Micropower operation with low cathode current requirements suitable for battery-powered designs
High precision fixed output voltage with tight initial tolerance
Compact surface-mount package optimized for space-saving PCB layouts

Applications

Portable electronic devices requiring low quiescent current
Battery-operated instrumentation systems
Space-constrained consumer electronics
Industrial control circuits needing stable reference voltages

Procurement Notes

Verify the specific suffix 'C' against official datasheets to confirm the exact accuracy grade and temperature coefficient specifications, as variations exist within the TS4041 family. Ensure compatibility with SOT-23-3 footprint requirements during procurement planning. Confirm RoHS compliance status for your region's regulatory needs.

Selection Notes

Select this component when a fixed 1.225V reference is required with minimal power draw. The SOT-23-3 package offers a compact solution compared to larger through-hole alternatives. Consider the 150ppm/°C temperature coefficient if operating across wide thermal ranges, and ensure the circuit design accommodates the 70 µA minimum cathode current for proper regulation.

Part Context

This part belongs to the TS4041 series of shunt voltage references from STMicroelectronics. The series includes variants with different accuracy grades and temperature coefficients. The TS4041 line is engineered for applications prioritizing low power consumption and small form factor, distinguishing it from higher-power or adjustable reference counterparts in the manufacturer's portfolio.
