Product details

What this shunt reference does for your rail

The Diodes Incorporated ATL432LIAQDBZR is an adjustable shunt voltage reference in a three-pin SOT-23-3 package. It holds the output at 2.5 V minimum up to 36 V maximum, trimmed to ±1% tolerance. The cathode current floor of 100 µA sets the minimum bias for regulation; output current is rated to 15 mA. Operating temperature spans -40°C to 125°C, covering industrial and automotive under-hood environments.

Active, ROHS3, no end-of-life concern

The ATL432LIAQDBZR carries an Active lifecycle status with ROHS3 compliance. This part is safe to specify into new production runs without obsolescence risk.

Frequently asked questions

Is ATL432LIAQDBZR a direct equivalent for TL431?

The ATL432LIAQDBZR is a functional equivalent to the TL431 family — both are adjustable shunt references with similar pinout and operating range. However, the ATL432LIAQDBZR specifies a ±1% tolerance and a 100 µA minimum cathode current; verify your TL431 variant's tolerance and bias current against your design. The SOT-23-3 package matches the common TL431 SOT-23 footprint.

Is ATL432LIAQDBZR RoHS compliant?

Yes. The ATL432LIAQDBZR is ROHS3 Compliant.
