TS432BIX

Overview

The TS432BIX is a three-terminal adjustable shunt voltage reference manufactured by Taiwan Semiconductor Corporation. It features a nominal reference voltage of 1.24V with an initial accuracy of ±0.5%. The device supports an operating voltage range up to 18V and can sink a cathode current of up to 100mA. Packaged in a SOT-23-3 surface-mount case, it offers specified thermal stability for reliable performance in power management applications.

Feature Summary

• Three-terminal adjustable shunt regulator architecture
• Specified thermal stability for consistent operation
• SOT-23-3 surface-mount package design

Applications

• Power supply voltage monitoring
• Portable equipment power management
• Battery-operated systems

Procurement Notes

Verify the specific suffix (e.g., RFG) against the datasheet to confirm tape-and-reel packaging details. Ensure the order quantity aligns with the manufacturer's standard packing quantity of 3,000 units per reel. Confirm RoHS compliance and REACH status requirements prior to finalizing procurement documentation.

Selection Notes

Select this component when a low-cost, thermally stable shunt reference is required for voltage regulation or sensing. The ±0.5% initial accuracy suits general-purpose applications. Consider the 100mA current capability for driving indicator LEDs or biasing other circuit elements within the 1.24V to 18V output range.

Part Context

This part belongs to the TS432xIX family, which includes variants like TS432AIX. These devices are designed as direct replacements for industry-standard adjustable shunt regulators. The TS432BIX specifically denotes the version with ±0.5% initial accuracy, distinguishing it from lower precision alternatives within the same product line.

Replacement Considerations

The TS432AIX is listed as a parameter-equivalent substitute. Verify that the alternative meets the required accuracy and thermal stability specifications for the specific application environment before implementation.
