TA76432S,F(J

Overview

The TA76432S,F(J) is a bipolar linear integrated circuit silicon monolithic shunt regulator from the TA76432 series. It features a precise internal reference voltage of 1.26 V, enabling operation at low voltages. The output voltage (VKA) is adjustable using two external resistors within a range of 1.26 V to 19 V. Key electrical characteristics include a reference voltage deviation of ±1.4% at 25°C and a typical temperature coefficient of 30 ppm/°C. The device operates with a cathode current range of 0.5 mA to 15 mA and an operating temperature range of -40°C to 85°C.

Feature Summary

• Adjustable high-precision shunt regulation capability
• Low temperature coefficient for stable performance
• Suitable for error amplification in switching systems

Applications

• Error amplifiers in 3V switching-regulator systems
• Temperature compensation circuits acting as Zener diodes
• General electronics applications including computers and measuring equipment

Procurement Notes

Verify the specific ordering suffix against official Toshiba Semiconductor and Storage documentation to confirm package type and packing configuration. Ensure compliance with environmental directives such as RoHS if required by the application. Confirm availability status directly with authorized distributors or the manufacturer, as product lifecycles may change.

Selection Notes

Select this component when a low-voltage, high-precision shunt regulator is required for feedback loops. Consider the LSTM through-hole package for prototyping or applications requiring radial mounting. Evaluate thermal dissipation requirements based on the maximum power dissipation rating and ambient operating conditions.

Part Context

This part belongs to the TA76432 series of adjustable high-precision shunt regulators manufactured by Toshiba Semiconductor and Storage. The series includes variants with different packages such as UFV, SMV, PW-Mini, and LSTM. The TA76432S specifically utilizes the LSTM lead-type package, distinguishing it from surface-mount options while sharing identical core electrical specifications.

Replacement Considerations

Direct substitutes within the same family include TA76432FT, TA76432FC, TA76432F, and TA76432FR. These share the same functional block but differ in physical packaging. Verify pin compatibility and thermal characteristics when substituting between package types.
