TS431BILT

Overview

The TS431BILT is a low-voltage, three-terminal adjustable shunt voltage reference manufactured by STMicroelectronics. It provides an output voltage range from 1.24 V to 6 V, set via two external resistors. The device features an initial accuracy of ±0.5% and a temperature coefficient of 100 ppm/°C. It operates with a cathode current range of 60 µA to 30 mA and supports a maximum input voltage of 10 V. The component is housed in a surface-mount SOT-23-5 package and is qualified under the AEC-Q100 automotive standard.

Feature Summary

Adjustable shunt voltage reference topology for precise regulation
Automotive qualification compliant with AEC-Q100 standards
Low output impedance typically stable for capacitive loads
Integrated ESD protection against human body and machine models

Applications

Regulating 3.3 V switching power supplies
Driving optocouplers in feedback loops
Precision voltage reference circuits in automotive electronics

Procurement Notes

Verify that the specific part number matches the required tolerance grade and package variant. Confirm AEC-Q100 qualification status if the application demands automotive reliability standards. Ensure the design accounts for the specified operating temperature range and cathode current limits to maintain stability and accuracy during procurement and integration.

Selection Notes

Select this component when a low-voltage adjustable reference is needed with automotive-grade reliability. The TS431BILT offers superior performance at lower voltages compared to TL431 equivalents. Consider the ±0.5% precision and 100 ppm/°C stability for applications requiring tight regulation within the 1.24 V to 6 V range.

Part Context

The TS431 series represents a family of low-voltage programmable shunt references designed to replace wider voltage devices like the TL431. The TS431BILT specifically denotes the B-grade version with ±0.5% initial accuracy. It is part of STMicroelectronics' portfolio aimed at compact, high-performance power management solutions for industrial and automotive sectors.
