Chip Enable Input. If logic high, current source outputs are enabled. If logic low, internal power is disconnected
from the VDD pin, disabling all functions. Logic threshold is 1.2 V.
Output Current Source. Two separate constant current outputs. Outputs may be loaded in any combination
without affecting regulation of the loaded output. If only one output is needed I
together. In this case the value of ISET resistor must be doubled. Compliance voltage range is 0.1V to 10V.
