TL1431AIZ-AP

Overview

The TL1431AIZ-AP is an adjustable shunt voltage reference manufactured by STMicroelectronics. It provides a programmable output voltage ranging from 2.5 V to 36 V using two external resistors. The device features a typical dynamic impedance of 0.2 Ω and supports a cathode current range from 1 mA to 100 mA. It offers high precision with a tolerance of ±0.4% and operates within a temperature range of -40°C to +125°C. The component is housed in a TO-92-3 through-hole package.

Feature Summary

Adjustable output voltage capability between 2.5 V and 36 V
High precision with ±0.4% initial accuracy
Wide operating temperature range suitable for automotive applications

Applications

Precision voltage references in power supply circuits
Linear regulators requiring stable reference voltages
Battery-operated equipment needing accurate monitoring

Procurement Notes

Verify the specific suffix AP indicates the tape and reel or specific packaging configuration if required for automated assembly, as standard variants may differ. Confirm the AEC-Q100 qualification status for automotive-grade reliability requirements. Ensure the TO-92-3 through-hole package aligns with the target PCB footprint and thermal management strategy.

Selection Notes

Select this component when a high-precision, adjustable shunt reference is needed for through-hole designs. The ±0.4% tolerance makes it suitable for applications demanding tight voltage regulation. Consider the 100 mA sink current capability for driving loads directly. Verify that the 36 V maximum input voltage meets the system's operational limits.

Part Context

This part belongs to the TL1431 family of adjustable shunt voltage references. It shares functional similarities with the TL431 but offers improved precision and wider temperature stability. The TL1431 series is widely used in industrial and automotive electronics where reliable voltage referencing is critical for system performance and safety.
