NOTES: (1) REF102s can be stacked to obtain voltages in multiples of 10V.
(2) The supply voltage should be between 10n + 1.4 and 10n + 26, where
n is
the number of REF102s. (3) Output current of each REF102 must not exceed
its rated output current of +10, −5mA. This includes the current delivered to
the lower REF102.
