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.","metaTitle":"ATL432LIAQDBZR adjustable shunt voltage reference, ±1%","metaDescription":"ATL432LIAQDBZR adjustable shunt voltage reference from Diodes Inc. ±1% tolerance, 100 µA cathode current, -40°C to 125°C.
