TS432ACX RFG

Overview

The TS432ACX RFG is an adjustable precision shunt voltage regulator manufactured by Taiwan Semiconductor Corporation. It operates within a cathode-to-anode voltage range of 1.24 V to 18 V and features an initial accuracy of 1%. The device has a maximum shunt current rating of 100 mA and a temperature coefficient of 50 PPM/°C. It is housed in a surface-mount SOT-23-3 package and supports AEC-Q101 automotive qualification standards.

Feature Summary

• Provides adjustable reference voltage functionality via external resistor divider
• Designed for high stability with low temperature coefficient characteristics
• Automotive-grade reliability compliant with AEC-Q101 standards

Applications

• Portable equipment power supply regulation
• DC-to-DC converter feedback loops
• Battery chargers and power management circuits

Procurement Notes

Verify the specific suffix 'RFG' against the manufacturer's official datasheet to confirm tape-and-reel packaging specifications and RoHS compliance status. Ensure the ordering part number matches the exact tolerance and package variant required for your design implementation.

Selection Notes

Select this component when an adjustable shunt regulator with 1% initial accuracy is required in a compact SOT-23-3 footprint. Consider the 100 mA maximum current capability and 18 V maximum operating voltage limits during circuit design to ensure safe operation margins.

Part Context

This part belongs to the TS432xx series of adjustable precision shunt regulators from Taiwan Semiconductor. It serves as a three-terminal voltage reference alternative to standard Zener diodes, offering superior performance in terms of temperature stability and dynamic impedance for precision analog applications.

Replacement Considerations

Compatible substitutes include TS432BCX RFG (0.5% accuracy) or TS432ACT A3 (through-hole TO-92). Verify pinout compatibility and electrical parameter alignment before substitution.
