PRODUCTION DATA.
To generate a constant and stable reference voltage, a current greater than IZ(MIN) must be sourced into the cathode of this device. This can be accomplished using a current regulating device such as LM334 or a simple resistor. For a resistor, its value should be equal to or greater than (Vsupply - Vreference) ÷ IZ(MIN) .
