The TL432x-Q1 devices are three-terminal adjustable shunt regulators with specified
thermal stability over the automotive temperature range. 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 TL432x-Q1 devices are 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 vs temperature ensures
good stability over the entire temperature range.
The devices are characterized for operation from –40°C to 125°C.
