TA76432S,T6MURAF(J

Overview

The TA76432S 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 1.26 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 cathode current range of 0.5 mA to 15 mA and an operating temperature range of -40°C to 85°C. The component is housed in an LSTM leaded package.

Feature Summary

• Provides a precise internal reference voltage for stable regulation performance
• Allows arbitrary adjustment of output voltage via external resistor networks
• Designed for low-voltage operation suitable for switching-regulator systems
• Capable of functioning as a zener diode for temperature compensation

Applications

• Error amplifiers in 3V switching-regulator systems
• Temperature compensation circuits utilizing zener diode characteristics
• General electronics applications including computers and office equipment

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and packing configuration. Confirm RoHS compatibility status directly with Toshiba sales representatives as indicated in the datasheet notes. Ensure design parameters respect absolute maximum ratings and thermal resistance values for the LSTM package to maintain reliability under specified operating conditions.

Selection Notes

Select this component when an adjustable high-precision shunt regulator is required for low-voltage applications. The LSTM package is suitable for through-hole mounting. Consider the minimum cathode current requirement for regulation and the dynamic impedance characteristics when designing feedback loops or stability compensation networks for the target application.

Part Context

The TA76432 series includes variants such as TA76432FT, TA76432FC, TA76432F, and TA76432FR, which share the same core electrical functionality but differ in packaging. The TA76432S specifically utilizes the LSTM leaded package, distinguishing it from surface-mount options like UFV, SMV, and PW-Mini used by other series members.

Replacement Considerations

Cross-reference with other TA76432 series members (TA76432FT, FC, F, FR) if package form factor changes are acceptable. Verify pinout compatibility and thermal dissipation requirements when substituting between different package types within the same functional family.
