... In the standard shunt configuration, the combination of low temperature coefficient (TC), sharp turn-on characteristics, low output impedance and programmable output voltage make this precision reference a perfect zener diode replacement. The AS1431 is characterized to operate over the full automotive tem- perature range of Ð55 to 125¡C and is now available in the SOT-23 (5L) package. CATHODE ...
