The ATL43xLI device is a three-terminal adjustable shunt regulator, with specified thermal stability over applicable automotive, commercial, and military temperature ranges. The output voltage can be set to any value between Vref (approximately 2.5 V) and 36 V, with two external resistors. These devices have a typical output impedance of 0.3 Ω. Active output circuitry provides a very sharp turn-on characteristic, making these devices excellent replacements 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 and TL432LI, with lower minimum operating current to help reduce system power consumption. The ATL432LI device has exactly the same functionality and electrical specifications as the ATL431LI device, but has a different pinout for the DBZ package. The ATL431LI is also offered in a tiny X2SON (1.00 mm x 1.00 mm) package which makes it ideal for space constraint applications.

The ATL431LI device is offered in two grades, with initial tolerances (at 25°C) of 0.5%, and 1%, for the B and A grade, respectively. In addition, low output drift versus temperature ensures good stability over the entire temperature range.

The ATL43xLIxQ devices are characterized for operation from –40°C to +125°C.
