TS4061BILT-1.225

Overview

The TS4061BILT-1.225 is a micropower shunt voltage reference manufactured by STMicroelectronics, providing a fixed output voltage of 1.225V with an initial accuracy tolerance of ±0.2%. It operates within an industrial temperature range of -40°C to +85°C and features a maximum temperature coefficient of 35ppm/°C. The device draws a typical operating current of 10µA at 25°C and supports a maximum cathode current of 15mA. It is housed in a compact SOT-23-3L surface-mount package.

Feature Summary

• Provides high precision voltage referencing with ±0.2% initial accuracy for stable circuit operation.
• Features ultra-low power consumption suitable for battery-operated or energy-constrained designs.
• Maintains stability when connected to capacitive loads without oscillation risks.

Applications

• Portable electronic devices requiring precise voltage monitoring
• Battery-powered instrumentation systems
• Data acquisition circuits needing accurate analog references

Procurement Notes

Verify the specific suffix 'IL' against official documentation to confirm the package type and tape-and-reel configuration. Confirm component status as obsolete or active through authorized channels before procurement planning. Ensure compatibility with existing PCB footprints for the SOT-23-3L package. Check for moisture sensitivity level requirements during storage and handling procedures.

Selection Notes

Select this component when space constraints necessitate a small surface-mount package like SOT-23-3L while maintaining high accuracy. Choose over standard references if low quiescent current is critical for extending battery life. Consider the ±0.2% tolerance and 35ppm/°C drift characteristics for applications demanding strict voltage stability across the industrial temperature range.

Part Context

This part belongs to the TS4061 family of precision micropower shunt voltage references from STMicroelectronics. The family includes variants with different accuracies (±0.1%, ±0.2%) and output voltages (1.225V, 1.25V). These components are designed for applications where size, power consumption, and precision are primary design drivers.

Replacement Considerations

Check for direct substitutes such as TS4061AILT-1.225 for higher accuracy or LM4041AIM3-1.2/NOP3 for alternative sourcing. Verify pinout and electrical parameter compatibility before substitution.
