The AIC431/TL431A/TL431 are 3-terminal ad-  
justable precision shunt regulators with guar-  
anteed temperature stability over the applica-  
ble extended commercial temperature range.  
The output voltage may be set at any level  
greater than 2.495V (VREF) up to 30V merely  
by selecting two external resistors that act as  
l Unconditionally Stable.  
l Precision Reference Voltage.  
AIC431 :2.495V ±0.5%  
TL431A :2.495V ±1.0%  
TL431  
:2.495V ±1.6%  
l Sink Current Capability: 200mA.  
l Minimum Cathode Current for Regulation: 250mA.  
a voltage divider network. These devices have  
a typical output impedance of 0.08W. Active  
output circuitry provides a very sharp turn-on  
characteristics, making these devices excel-  
lent improved replacements for zener diodes  
in many applications.  
l Equivalent Full-Range Temperature Coefficient:  
50 ppm/°C.  
l Fast Turn-On Response.  
l Low Dynamic Output Impedance: 0.08W.  
l Adjustable Output Voltage.  
l Low Output Noise.  
l Space Saving SOT-89, SOT-23, TO-92 and SO8  
The precise ±0.5% reference voltage toler-  
ance of the AIC431 makes it possible in  
many applications to avoid the use of a vari-  
able resistor, consequently saving cost and  
eliminating drift and reliability problems asso-  
ciated with it.
