circuit comes into regulation.
It is imperative that the V+ supply (Pin 16) be a good
ac ground for stability reasons. If this pin is not well
filtered (by a 1000 pF capacitor AT THE IC), any
>75 ㏀. The VCC and VB regulated voltages go to 0.0 A
Logic "1" level in the range of 1.6 V to 11 V deselects
when the chip is deselected. Leaving Pin 18 open is the
chip, and the resulting supply current (at V+) is
equivalent to a Logic "0" (chip enabled).
