TL432BQDBZRQ1
可调式精密并联稳压器 ADJUSTABLE PRECISION SHUNT REGULATORS
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.
