Description

The TPR433 and TPR434 are 3-terminal adjustable shunt

voltage references. The output voltage of both devices can

be set to any value within the range from VREF to 36 V with

an external feedback resistor network.

The TPR433 and TPR434 have exactly same electrical

performance and same package but different pin orders.

The device provides a 0.2-Ω output impedance and

a quick turn-on characteristic, making it an excellent

replacement for ordinary Zener diode in many applications.

The TPR433 and TPR434 support a wide output current

range from 1 to 80 mA with a SOT23G-3 package. Both

devices are qualified with the operating temperature range

from −40°C to +125°C.
