ATL431LIBIDQNR

Overview

The ATL431LIBIDQNR is a low-IQ programmable shunt regulator from Texas Instruments, housed in an X2SON-4 package. It offers an adjustable output voltage range of 2.5 V to 36 V with an initial accuracy of 1% and a temperature coefficient of 66 ppm/°C. The device supports a maximum cathode current of 15 mA and operates within a temperature range of -40°C to +125°C.

Feature Summary

Low quiescent current operation for power efficiency
Adjustable output voltage via external resistors
High thermal stability across wide temperature ranges

Applications

Battery-powered equipment
Power supply circuits
DC-to-DC converters

Procurement Notes

Verify the specific suffix 'DQNR' confirms the X2SON-4 package and reel packaging format. Ensure the application requires the 1% initial accuracy specification rather than tighter tolerances. Confirm that the operating environment stays within the specified -40°C to +125°C range for reliable performance.

Selection Notes

Select this component when a compact surface-mount solution is required for precision voltage referencing. It is suitable for designs needing low standby current and wide input voltage compatibility. Consider the X2SON-4 footprint constraints during PCB layout planning.

Part Context

This part belongs to the ATL431LI series, which are automotive-grade compatible programmable shunt regulators. The series provides a robust alternative to standard Zener diodes, offering better temperature stability and lower dynamic impedance for precise regulation tasks.

Replacement Considerations

Check pinout compatibility if substituting with other TL431 variants. Verify that the replacement device meets the same 15 mA cathode current limit and 36 V maximum voltage rating.
