TS432AIX RFG

Overview

The TS432AIX RFG is a three-terminal adjustable shunt voltage reference manufactured by Taiwan Semiconductor in an SOT-23 package. It features a programmable output voltage range from approximately 1.24V to 18V using two external resistors. The device specifies a reference voltage of 1.24V with ±1% accuracy and operates with a continuous cathode current up to 100mA. Key electrical parameters include a typical dynamic output impedance of 0.2Ω, a minimum operating cathode current of 60µA, and an equivalent full-range temperature coefficient of 50ppm/ºC.

Feature Summary

Precision reference voltage with specified thermal stability for accurate regulation
Fast turn-on response characteristic suitable for replacing Zener diodes
Low dynamic output impedance ensuring stable performance across load variations

Applications

Switching Mode Power Supplies (SMPS)
Lighting systems
Telecommunication equipment
Home appliances

Procurement Notes

Verify the specific ordering code suffix against manufacturer documentation to confirm packaging details and compliance status. Ensure that the selected variant matches the required accuracy grade and environmental specifications for the intended application. Cross-reference the datasheet version to confirm all electrical characteristics are current before finalizing procurement orders.

Selection Notes

Select this component when a low-cost, high-precision shunt regulator is required for voltage monitoring or reference applications. Consider the SOT-23 package size for space-constrained designs. Evaluate the stability boundary conditions regarding load capacitance to prevent oscillation during startup or transient phases. Ensure the design accommodates the minimum cathode current requirements for reliable operation.

Part Context

This part belongs to the TS432xIX series of programmable shunt voltage references. The series includes variants such as TS432BIX, which offers tighter initial accuracy. These devices are designed as direct replacements for standard Zener diodes in various electronic circuits, providing superior thermal stability and lower dynamic impedance compared to traditional discrete solutions.
