... V IN DROOP+ The output resistances for the positive and negative charge pumps are tested and specified separately. The positive charge pump is tested with V- unloaded. The negative charge pump is tested with V+ supplied from an external source, isolating the negative charge pump. Current draw from either supplied by the reservoir capacitor alone during one half cycle of the clock ...
