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.
This part is safe to specify into new production runs without obsolescence risk.
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.
Yes. The ATL432LIAQDBZR is ROHS3 Compliant.
