TL432B-Q1 (ACTIVE) Automotive adjustable precision shunt regulator

Automotive adjustable precision shunt regulator - TL432B-Q1
Datasheet
 

Description

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.
