    LA431 ADJUSTABLE PRECISIONSHUNT REGULATION General Description The LA 431 is a low voltage three terminal adjustable shunt regulator with a guaranteed thermal stability over applicable temperature ranges. The output voltage can be set to any value between 2.495V (VREF) to 36V with two external resistors (please refer application circuit). The high precise Reference voltage tolerance is available in two grades: ±0.4% and ±1.0%. This device has a typical minimum cathode current of 0.1 mA. Active output circuitry provides a very sharp turn on characteristic, making this device excellent replacement for Zener diodes in many applications. Features • Precision reference voltage : − LA431O : 2.495V±0.4% − LA431N : 2.495V±1.
