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 V REF 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.

The average full-range temperature coefficient of the reference input voltage αVREF is defined as αVREF ppm °C = VI DEV /VREF, 25°C ΔTA × 106. Where, VREF,25°C is the typical value at room temperature of 25°C, ΔTA is the rated operating ambient temperature range of the device. αVREF is positive or negative, depending on whether minimum value or maximum value of the VREF occurs at the lower temperature.

When the device is operating with two external resistors, the total dynamic impedance of the circuit is Z′ = ΔV ΔI , which is approximately equal to ZKA 1 +R1 R2 .
