Overview
The TA76L431S(T6SOY,AQ) is a bipolar linear integrated circuit silicon monolithic adjustable high-precision shunt regulator manufactured by Toshiba Semiconductor and Storage. It features a precise internal reference voltage of 2.49 V, enabling operation at low voltages. The device allows the output voltage (VKA) to be set arbitrarily using two external resistors within a range from the reference voltage up to 19 V. It operates with a minimum cathode current for regulation of 0.5 mA maximum and supports an operating temperature range from -40°C to 85°C.
Feature Summary
- Adjustable high-precision shunt regulator functionality
- Precise internal reference voltage of 2.49 V
- Output voltage settable via external resistors
Applications
- Error amplification circuits for switching power supplies
- Temperature compensation applications acting as Zener diodes
- General electronics applications including computers and measuring equipment
Procurement Notes
Verify the exact suffix T6SOY,AQ against official Toshiba documentation to confirm package type and environmental compliance status. Confirm availability as standard distribution channels may list generic variants like TA76L431S(Q). Ensure design accounts for static electricity precautions due to internal MOS elements.
Selection Notes
Select this component when a stable 2.49 V reference is required in a through-hole LSTM package. Consider the 0.5 mA minimum cathode current requirement for regulation stability. Evaluate thermal resistance characteristics if mounting on substrates other than the specified glass epoxy board dimensions.
Part Context
This part belongs to the TA76L431 series of adjustable high-precision shunt regulators. The 'S' designation indicates the LSTM leaded package variant, distinct from the UFV surface-mount FT version. The series is designed for general-purpose voltage referencing and error amplification in low-voltage systems.
Replacement Considerations
TA76L431FT serves as the surface-mount equivalent in the same series. Verify pinout compatibility between LSTM and UFV packages before substitution. Check specific ordering suffixes for RoHS compliance variations.
