The ATL43xLI-Q1 is a three-terminal adjustable shunt regulator, with specified thermal stability over applicable automotive, commercial, and military temperature ranges. Its output voltage can be set to any value between Vref (approximately 2.5 V) and 36 V with two external resistors. The device has a typical output impedance of 0.3 Ω. Its active output circuitry provides a very sharp turn-on characteristic, making it an excellent replacement for Zener diodes in many applications, such as onboard regulation, adjustable power supplies, and switching power supplies. This device is a pin-to-pin alternative to the TL431LI-Q1 and TL432LI-Q1, with lower minimum operating current to help reduce system power consumption. The ATL432LI-Q1 has exactly the same functionality and electrical specifications as the ATL431LI-Q1, but has a different pinout for the DBZ package.
The ATL431LI-Q1 is offered in two grades, with initial tolerances (at 25°C) of 0.5%, and 1%, for the B and A grade, respectively. The ATL43xLI-Q1 is characterized for operation from –40°C to +125°C, and its low output drift versus temperature ensures good stability over the entire temperature range.
