JIANGSU CHANGJING ELECTRONICS TECHNOLOGY CO., LTD  
Adjustable Precision Zener Shunt Regulator  
CJ431D / CD431D Voltage References  
3 Features  
1 Introduction  
The CJ431D / CD431D is a three terminal adjustable  
precision Zener shunt regulator with guaranteed  
thermal stability over a full operation range. It has  
sharp turn-on characteristics, low temperature  
coefficient and low output impedance, and the output  
voltage can be set to any value between VREF and  
maximum cathode voltage by selecting two external  
resistors acting as voltage divider networks, which  
makes them ideal substitutes for Zener diodes in  
applications such as switching power supplies,  
chargers and other adjustable regulators.  
Adjustable Output Voltage: VREF to 36 V  
Reference Voltage Tolerance at 25°C:  
Available in ±0.4% or ±0.8%  
Sink-current Capability: 1 ~ 100mA  
Operation Ambient Temperature:  
-40 ~ 125°C  
Low Temperature Drift: 4.5mV (Typ.)  
Excellent Temperature Coefficient:  
20 ppm/°C over the full temperature  
Low Dynamic Output Resistance:  
0.15Ω (Typ.)  
Fast Turn-on Response  
Low Output Noise
