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 a voltage divider network. These devices have a typical output impedance of 0.08 Ω. Active output circuitry provides a very sharp turn-on characteristics, making these devices excel- lent improved replacements for zener diodes in many applications. 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. |
