Positive_variable_voltage_reference_VSUBOUT_SUB_is_lower_than_reference_zener

This circuit is suited for high-precision extended-temperature service, if V+ is reasonably constant (Because IZ does depend on V+). R1 through R4 are chosen to provide optimum zener current for minimum zener temperature coeffi-cient (TC), and to minimize error of Ibis.
