stability over a full operation range. These monolithic ICs
voltage reference operate as a low temperature coefficient
Zener which is programmable from Vref to 18V with two external
resistors. These devices exhibit a wide operating current range
of 80µA to 50/100mA with a typical dynamic impedance of 0.05 to
0.22Ω. The characteristics of these references make them excellent
programmable shunt regulators with guaranteed thermal
