TA76432S(F,M)

Overview

The TA76432S(F,M) 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 output voltage (VKA) can be set arbitrarily using two external resistors within the range of VREF to 19 V. The device operates with a minimum cathode current for regulation of 0.5 mA max and functions effectively as an error amplifier in switching-regulator systems or as a Zener diode for temperature compensation.

Feature Summary

Provides a precise internal reference voltage of 1.26 V with a small temperature coefficient.
Allows arbitrary adjustment of output voltage via two external resistors.
Operates as an error amplifier in low-voltage switching-regulator systems.
Functions as a Zener diode for performing temperature compensation.

Applications

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

Procurement Notes

Verify RoHS compatibility status through official Toshiba sales representatives, as indicated by lot number markings. Confirm package type LSTM corresponds to lead-type radial tape packaging. Ensure design adheres to absolute maximum ratings and derating concepts specified in the Toshiba Semiconductor Reliability Handbook to maintain product reliability under heavy loads.

Selection Notes

Select the TA76432S variant when a leaded package (LSTM) is required for through-hole mounting. This model offers a typical thermal resistance of 156 ºC/W and supports an operating temperature range from -40°C to 85°C. Consider the ultra-thin UFV or SMV packages if surface-mount space constraints are critical, as they offer lower weight and different thermal characteristics compared to the LSTM package.

Part Context

The TA76432 series includes multiple package options such as UFV, SMV, PW-Mini, and LSTM. The TA76432S specifically utilizes the LSTM package, which is a lead-type configuration. Other variants like TA76432FT and TA76432FC offer surface-mount solutions with distinct thermal and physical properties. All series members share the core functionality of a 1.26V adjustable high-precision shunt regulator.
