DESCRIPTION/ORDERING INFORMATION

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 V_ref(approximately 2.5 V)

and 36 V with two external resistors (see Figure 17). 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.
