Figure 16). This device has a typical output

impedance of 0.2 Ω. Active output circuitry

provides a very sharp turnon characteristic,

making the device an excellent replacement for

zener diodes and other types of references in

applications such as onboard regulation,

adjustable power supplies, and switching power

supplies.
