Overview
The TS821IZ is a micropower shunt voltage reference manufactured by STMicroelectronics, providing a stable 1.225V output. It features an initial accuracy of 2% at 25°C and a maximum temperature coefficient of 120 PPM/°C. The device operates within an industrial temperature range of -40°C to +85°C and utilizes an SOT-23-3 surface-mount package. Key electrical parameters include a maximum operating supply current of 12 mA and a minimum shunt current of 45 uA.
Feature Summary
- Provides a stable 1.225V reference voltage suitable for space-saving designs
- Ultra-low operating current consumption ideal for power-restricted applications
- High stability when used with capacitive loads
Applications
- Battery-powered systems requiring low power consumption
- Portable instrumentation
- Data acquisition systems
- Temperature measurement circuits
Procurement Notes
Verify the specific suffix 'IZ' against official STMicroelectronics documentation to confirm grade and packaging details. Confirm end-of-life status as some sources indicate obsolescence for related variants. Ensure compatibility with SOT-23-3 footprint requirements during procurement planning.
Selection Notes
Select this component for applications demanding high precision in a compact form factor. The 2% accuracy and low temperature coefficient make it suitable for general-purpose references. Consider the A or B grades if tighter tolerances are required, as these offer improved accuracy specifications compared to the standard version.
Part Context
The TS821 belongs to the TS821 series of micropower shunt voltage references. It is designed to replace older discrete reference solutions in modern electronics. The series is characterized by its ability to maintain performance across wide temperature ranges while minimizing power usage in portable devices.
Replacement Considerations
Check for direct pin-compatible substitutes within the same family, such as TS821IL or TS821IY, ensuring voltage and accuracy grades match. Verify availability as the product line may be subject to discontinuation notices.
