ATL432LIAQDBZR

Overview

The ATL432LIAQDBZR is an automotive-grade, high-bandwidth, low-quiescent current programmable shunt regulator manufactured by Texas Instruments. It operates within a temperature range of -40°C to 125°C and utilizes a SOT-23 package. The device features an adjustable output voltage range from approximately 2.5V to 36V, with a reference voltage tolerance of ±1% at 25°C. It supports a cathode current range of 80µA to 15mA and maintains an output impedance typical of 0.2Ω.

Feature Summary

Automotive-grade reliability designed for harsh environments
High bandwidth performance for fast transient response
Low quiescent current operation for energy efficiency
All-capacitor stability without requiring minimum load

Applications

Automotive power supply regulation
Battery management systems
DC-DC converter feedback loops
Voltage reference in automotive ECUs

Procurement Notes

Verify the specific suffix 'Q1' indicates automotive qualification status against the official datasheet. Confirm the package marking code matches the intended application requirements. Ensure the ordering part number aligns with the required tape and reel specifications for automated assembly processes.

Selection Notes

Select this component when automotive AEC-Q100 compliance is mandatory alongside high-speed regulation needs. Compare the low IQ specification against standard TL432 variants to ensure system power budget constraints are met. Verify that the SOT-23 footprint fits the PCB layout constraints compared to larger packages.

Part Context

This part belongs to the ATL43x family, which extends the standard TL43x series with automotive qualifications. It shares functional similarities with the TL432LIAQDBZR but offers optimized bandwidth characteristics. The device serves as a direct replacement for Zener diodes in precision applications requiring better stability and adjustability.

Replacement Considerations

The TL432LIAQDBZR is a compatible alternative within the same family. Verify pinout compatibility between DBZ and DBVR packages if substituting with non-automated versions.
