3 Description
The TL431LI / TL432LI are pin-to-pin alternatives
to TL431 / TL432. TL43xLI offers better stability,
lower temperature drift (VI(dev)), and lower
reference current (Iref) for improved system
The TL431 and TL432 devices are three-terminal
adjustable shunt regulators, 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 0.2 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. The
TL432 device has exactly the same functionality and
electrical specifications as the TL431 device, but has
different pinouts for the DBV, DBZ, and PK packages.
Both the TL431 and TL432 devices are offered in
three grades, with initial tolerances (at 25°C) of
0.5%, 1%, and 2%, for the B, A, and standard
grade, respectively. In addition, low output drift versus
temperature ensures good stability over the entire
temperature range.
The TL43xxC devices are characterized for operation
from 0°C to 70°C, the TL43xxI devices are
characterized for operation from –40°C to 85°C, and
the TL43xxQ devices are characterized for operation
from –40°C to 125°C.
