Overview
The TA76432S(TE6,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 device allows arbitrary output voltage setting using two external resistors, with an operating range from the reference voltage up to 19 V. It operates within a temperature range of -40°C to 85°C and utilizes the LSTM leaded package.
Feature Summary
- Adjustable output voltage capability via external resistors
- High-precision internal reference voltage for stable regulation
- Low minimum cathode current requirement for efficient regulation
- Suitable for use as error amplifiers in switching-regulator systems
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 the specific ordering suffixes against the manufacturer's documentation to ensure correct 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 reliable operation.
Selection Notes
Select this component when a high-precision shunt regulator with adjustable output is required for low-voltage applications. Consider the LSTM package for through-hole mounting requirements. Evaluate stability boundaries regarding load capacitance and cathode current to ensure proper circuit performance within the specified operating temperature range.
Part Context
This part belongs to the TA76432 series of adjustable high-precision shunt regulators. The series includes variants such as TA76432FT, TA76432FC, TA76432F, and TA76432FR, which differ primarily in package types like UFV, SMV, and PW-Mini. All variants share the core electrical characteristics of a 1.26 V reference voltage.
Replacement Considerations
Direct substitutes within the same family include TA76432S(F). For different packages, consider TA76432FT, TA76432FC, TA76432F, or TA76432FR, noting that pin assignments and physical dimensions vary significantly between package types.
