TA76L431S(T6SOY,QM

Overview

The TA76L431S is a bipolar linear integrated circuit manufactured by Toshiba Semiconductor and Storage, functioning as an adjustable high-precision shunt regulator. It features a precise internal reference voltage of 2.49 V, allowing operation at low voltages. The output voltage (VKA) can be set arbitrarily using two external resistors within the range of 2.49 V to 19 V. Key electrical characteristics include a minimum cathode current for regulation of 0.5 mA maximum and a dynamic impedance of 0.5 Ω maximum. The device operates within an ambient temperature range of -40°C to 85°C.

Feature Summary
