TL432CDBZTG4

Overview

The TL432CDBZTG4 is an adjustable precision shunt regulator manufactured by Texas Instruments, housed in a SOT-23-3 surface-mount package. It features an initial accuracy of ±2% and operates within a temperature range of -40°C to +85°C. The device supports a maximum series input voltage of 37 V and a maximum cathode current of 100 mA, with a minimum operating current of 600 µA. Its maximum output voltage reaches 36 V, and it exhibits a temperature coefficient of 34 PPM/°C.

Feature Summary

• Provides precise adjustable reference voltage functionality for shunt regulation applications
• Ensures stable performance across industrial temperature ranges with defined thermal stability
• Supports high sink current capability for effective power management control

Applications

• Linear regulator circuits requiring precise voltage referencing
• Adjustable power supply designs needing stable shunt regulation
• Switching power supplies utilizing feedback loop stabilization
• Battery charger systems requiring accurate voltage monitoring

Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and lead-free manufacturing status as per Texas Instruments documentation. Confirm the SOT-23-3 package outline matches your PCB footprint requirements. Ensure the ±2% tolerance aligns with your circuit's precision needs. Check for any recent Product Change Notifications regarding packaging or material composition updates before finalizing procurement specifications.

Selection Notes

Select this component when an adjustable shunt regulator with ±2% initial accuracy is required in a compact SOT-23-3 package. It is suitable for applications demanding operation up to 37 V input and 100 mA sink current. Consider the 34 PPM/°C temperature coefficient for thermal stability requirements. Compare against TL431 variants if fixed reference voltages or different accuracy grades are needed instead of adjustable outputs.

Part Context

This part belongs to the TL432 family of low-voltage adjustable precision shunt regulators from Texas Instruments. It serves as a direct replacement for legacy adjustable references in space-constrained designs. The device integrates a bandgap reference and error amplifier to provide stable regulation. It is widely used in consumer electronics and industrial equipment where small form factor and precise voltage control are critical design parameters.

Replacement Considerations

The TL432CDBZR is the non-RoHS compliant equivalent without the G4 suffix. Verify pinout compatibility when substituting with other TL432 variants. Ensure that any alternative part maintains the same SOT-23-3 package dimensions and electrical characteristics for direct board-level replacement.
