Overview
The TS431AIZT is a low-voltage, three-terminal adjustable shunt voltage reference manufactured by STMicroelectronics. It operates within an input voltage range of 2.50V to 36.0V and provides an adjustable output voltage from 2.495V to 36V. The device features a maximum cathode current of 100 mA and maintains an initial accuracy tolerance of ±1%. It is housed in a TO-92-3 through-hole package and supports an operating temperature range from -40°C to 105°C.
Feature Summary
- Adjustable shunt voltage reference topology allowing output setting via external resistors
- High precision with 1% initial accuracy tolerance for stable reference performance
- Low voltage operation capability suitable for driving optocouplers in switching power supplies
Applications
- Regulating 3.3 V switching power supplies
- Driving optocouplers in feedback loops
- General purpose voltage reference circuits
Procurement Notes
Verify the specific part number suffix against official STMicroelectronics documentation to confirm package type and electrical specifications. Ensure the component matches the required thermal grade and pinout configuration for your PCB layout. Cross-reference datasheet revisions to confirm compliance with current RoHS and REACH standards before finalizing procurement orders.
Selection Notes
Select this component when a low-cost, high-precision shunt reference is needed for standard voltage regulation tasks. It serves as a direct replacement for TL431 variants in many designs but offers optimized performance at lower voltages. Consider the TO-92-3 package constraints and the 100 mA current limit when designing the biasing network for your specific application requirements.
Part Context
This component belongs to the TS431 family of adjustable shunt voltage references designed by STMicroelectronics. The TS431 series is engineered to operate at lower voltages and currents compared to traditional TL431 devices, making it ideal for modern low-power applications. It provides a reliable, cost-effective solution for precision voltage referencing in compact electronic systems.
Replacement Considerations
Direct substitutes include the TL431AIZT and TS431AIZ-AP from STMicroelectronics. Other compatible options may include equivalent shunt references from Texas Instruments such as the TL1431CLPR, provided pinouts and electrical characteristics are verified.
