TL432ACDBVRE4

Overview

The TL432ACDBVRE4 is an adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a voltage range of 2.495 V to 36 V and provides an initial accuracy of 1%. The device features a maximum temperature coefficient of 92 ppm/°C and supports a maximum cathode current of 100 mA with a minimum operating current of 600 µA. It is housed in a surface-mount SOT-23-5 package and functions reliably across an industrial temperature range from 0°C to +70°C.

Feature Summary

• Provides stable reference voltage via adjustable shunt regulation topology
• Ensures high precision with 1% initial accuracy specification
• Supports wide input voltage operation up to 36 V

Applications

• Precision voltage references in power supply circuits
• Voltage monitoring and threshold detection systems
• Battery-powered equipment requiring stable reference levels

Procurement Notes

Verify the specific suffix E4 indicates lead-free compliance against the official datasheet. Confirm the SOT-23-5 package dimensions match the target PCB footprint. Ensure the 1% accuracy and 92 ppm/C temperature coefficient meet the design requirements for the intended application environment.

Selection Notes

Select this component when a low-cost, high-accuracy adjustable reference is required in a compact surface-mount form factor. It serves as a direct replacement for standard TL431 variants where automotive or extended reliability is not explicitly mandated by the Q-grade designation. Consider the 100 mA sink capability for driving indicator loads or feedback networks directly.

Part Context

This part belongs to the TL432 family of adjustable shunt regulators from Texas Instruments. It shares functional similarities with the TL431 but is optimized for specific packaging and performance characteristics. The device integrates a 2.5 V bandgap reference with error amplification to maintain precise output regulation under varying load conditions.

Replacement Considerations

The TL432ACDBVR is a compatible alternative within the same series. Verify pinout compatibility and electrical specifications before substitution.
