TS822ILT

Overview

The TS822ILT is a low-power shunt voltage reference manufactured by STMicroelectronics, providing a stable 2.5V output. It operates within an industrial temperature range of -40°C to +85°C and features a maximum temperature coefficient of 100 ppm/°C. The device offers high precision with ±1% initial accuracy at 25°C for the A-grade variant. Key electrical specifications include a typical operating current of 40µA, a maximum shunt current of 15mA, and a minimum shunt current of 50µA. It is housed in a compact SOT-23-3 surface-mount package.

Feature Summary

• Provides a stable 2.5V reference voltage suitable for space-constrained designs
• Ultra-low power consumption ideal for battery-operated applications
• High stability when used with capacitive loads
• Industrial temperature range operation from -40°C to +85°C

Applications

• Portable instrumentation requiring low power supply references
• Battery-powered measurement devices

• Precision analog circuits needing stable voltage benchmarks

Procurement Notes

Verify the specific grade suffix (AILT) corresponds to the required ±1% accuracy level during procurement. Confirm the SOT-23-3 package dimensions match the PCB footprint requirements. Ensure the operating environment stays within the specified -40°C to +85°C industrial temperature range. Check datasheet limits for shunt current to prevent exceeding the 15mA maximum rating.

Selection Notes

Select this component when a stable 2.5V reference is needed with minimal quiescent current. The A-grade version ensures tighter tolerance compared to standard variants. Consider the SOT-23-3 package for board space optimization. Verify that the application load conditions allow for stable operation with the required capacitive loading characteristics defined in the official documentation.

Part Context

The TS822 belongs to STMicroelectronics' family of micro-power shunt voltage references. It shares design similarities with the TS821 (1.225V) but provides a higher 2.5V output. This series is engineered for applications where power efficiency and physical size are critical constraints, offering a robust solution for portable and industrial electronics.

Replacement Considerations

Public confirmed substitute part numbers: TS822AI (Standard Tape & Reel), TS822IL (Cut Tape). Verify pinout compatibility and thermal performance before substitution.
