TS4041EILT-1.2

Overview

The TS4041EILT-1.2 is a micropower shunt voltage reference manufactured by STMicroelectronics, providing a stable 1.225V output. It features an initial accuracy of ±0.5% at 25°C and a maximum temperature coefficient of 150ppm/°C. The device operates with an ultra-low current consumption of 65µA maximum at 25°C and supports a cathode current up to 12mA. It functions within an industrial temperature range of -40°C to +85°C and is housed in a compact SOT-23-3 surface-mount package.

Feature Summary

Provides a fixed 1.225V reference voltage with high precision for accurate circuit monitoring
Ultra-low operating current ensures minimal power dissipation in battery-powered designs
Maintains stability when connected to capacitive loads without oscillation
Compact SOT-23-3 package facilitates space-saving PCB layouts

Applications

Battery-operated portable devices requiring low quiescent current
Precision analog-to-digital converter (ADC) reference sources
Temperature-compensated sensor circuits
Portable instrumentation and metering equipment

Procurement Notes

Verify the specific suffix 'E' indicates the ±0.5% tolerance grade, distinct from standard variants. Confirm the 'IL' designation corresponds to the SOT-23-3 package type and reel packaging specifications. Ensure compatibility with RoHS3 compliance requirements for the target assembly process.

Selection Notes

Select this component when a fixed 1.225V reference is required with tighter initial accuracy than standard ±1% versions. The low current consumption makes it suitable for energy-constrained applications where standby power must be minimized. Verify that the 150ppm/°C temperature coefficient meets the system's thermal drift requirements across the specified industrial temperature range.

Part Context

The TS4041 belongs to STMicroelectronics' family of micropower shunt voltage references. This series includes variants with different output voltages and tolerance grades, all sharing the core architecture of a bandgap reference element optimized for low power operation. The TS4041 specifically targets the 1.225V output segment of this portfolio.
