TL432AIL3T

Overview

The TL432AIL3T is an adjustable shunt voltage reference integrated circuit manufactured by STMicroelectronics. It operates within a supply voltage range of 2.5 V to 36 V and provides an output voltage adjustable from 2.495 V up to the maximum supply limit. The device features a typical cathode current of 80 µA and can sink a maximum output current of 100 mA. It offers a tolerance of ±1% and functions across a temperature range of -40°C to 105°C. The component is housed in a compact SOT-23-3 surface-mount package.

Feature Summary

• Adjustable output voltage capability spanning from 2.495 V to 36 V
• High accuracy with a specified tolerance of ±1%
• Low quiescent cathode current consumption for power efficiency
• Robust thermal performance suitable for industrial operating temperatures

Applications

• Precision voltage regulation in portable electronic devices
• Reference voltage source for analog-to-digital converters
• Linear regulator feedback networks
• Battery-powered equipment requiring stable voltage references

Procurement Notes

Verify the specific suffix 'AIL3T' to confirm the tape-and-reel packaging format and temperature grade. Ensure the procurement channel sources directly from authorized distributors to guarantee authenticity. Cross-reference the datasheet revision date against your design requirements to confirm compliance with current specifications. Confirm RoHS3 compliance status if required by your manufacturing standards.

Selection Notes

Select this component when a low-cost, high-accuracy adjustable reference is needed in a small footprint. The ±1% tolerance makes it suitable for applications where standard zener diodes lack precision. Consider the 100 mA sink capability for driving moderate loads directly. The wide operating voltage range allows flexibility in system design without needing multiple fixed-voltage references.

Part Context

This part belongs to the TL432 family of programmable shunt voltage references. It serves as a cost-effective alternative to more complex voltage regulator ICs. The SOT-23-3 package allows for space-constrained designs common in modern consumer electronics. It complements STMicroelectronics' broader portfolio of power management solutions.

Replacement Considerations

Check for direct pin-compatible alternatives such as the TL432BIL3T or other manufacturers' equivalents like LM4040 series devices. Verify that substitute components meet the same ±1% tolerance and 36 V maximum voltage rating. Ensure the replacement supports the required SOT-23-3 package and industrial temperature range.
