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. ATL431LIAIDBZR
