TL432BIDBZT

Overview

The TL432BIDBZT is an adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a voltage range of 2.495 V to 36 V with an initial accuracy tolerance of ±0.5%. The device supports a maximum cathode current of 100 mA and withstands input voltages up to 37 V. It is housed in a SOT-23-3 surface-mount package and functions across a temperature range of -40 °C to +85 °C.

Feature Summary

• Provides adjustable reference voltage output via external resistors
• Delivers high initial accuracy for precise circuit regulation
• Features low dynamic output impedance for stable performance

Applications

• Portable equipment power supplies
• DC-to-DC converters
• Internal reference voltage sources

Procurement Notes

Verify the specific suffix 'BI' confirms the ±0.5% tolerance grade and commercial temperature range (-40°C to +85°C). Confirm the DBZT designation corresponds to the SOT-23-3 tape-and-reel packaging format required for automated assembly processes.

Selection Notes

Select this component when a compact, low-cost adjustable reference is needed with tighter initial accuracy than standard variants. Ensure the operating environment remains within the specified commercial temperature limits and that the SOT-23-3 footprint fits the design constraints.

Part Context

This part belongs to the TL432 family of three-terminal adjustable shunt regulators. It shares functional similarities with the TL431 but utilizes a distinct pinout configuration compatible with SOT-23 and similar small-outline packages, facilitating space-efficient designs.

Replacement Considerations

TL432AIDBZT offers identical functionality with ±1% accuracy. TL432CIDBZT provides ±2% accuracy. Verify pinout compatibility when substituting with other TL43x series devices.
