Digital VDD.

Chip Enable pin. No signal (0V output) at high makes

power consumption minimum.

Independent Constant-Voltage Source Output pin

using band gap reference. Stable voltage

independent of the fluctuation for supply voltage can

be obtained by connecting to VREF. See Application

Circuit 2 for details.
