TS431CS RLG

Overview

The TS431CS RLG is a low-voltage, three-terminal adjustable shunt voltage reference manufactured by Taiwan Semiconductor Corporation. It operates within a voltage range of 1.24 V to 6 V and supports cathode currents from 60 μA to 30 mA. The device features an output impedance of 0.2 Ω and a temperature coefficient of 100 ppm/°C. It is housed in an 8-pin SOP package with tape and reel packaging.

Feature Summary

• Adjustable shunt voltage reference topology
• Low voltage operation capability
• Wide operating range cathode current
• Typically stable for capacitive loads

Applications

• General purpose voltage regulation
• Power supply feedback loops
• Portable equipment power management

Procurement Notes

Verify the specific suffix 'RLG' against official Taiwan Semiconductor documentation to confirm exact pinout, tolerance grade, and environmental compliance status. Ensure the 8-pin SOP package matches the target PCB footprint and that the tape and reel format aligns with automated assembly requirements.

Selection Notes

Select this component when a low-voltage adjustable reference is required in an 8-pin surface-mount package. Consider its wide cathode current range and stability with capacitive loads for applications needing robust performance in compact designs without requiring automotive qualification.

Part Context

This part belongs to the TS431 family of programmable shunt references. While similar devices like the TS431I or TS431AIYLT exist in SOT-23 packages, the TS431CS RLG utilizes an 8-pin SOP configuration, offering different thermal and spatial characteristics suitable for specific board layouts.

Replacement Considerations

Direct substitutes include other TS431 variants such as TS431CXRF or TS431CXRFG. Verify package compatibility (SOP vs SOT-23) and electrical parameter alignment before substitution.
