ENABLE Function
typically, (see Figure 10 or Figure 11), the IC is disabled and
enters a sleep state where the device draws less than 30 mA
from supply. When the V

** C2 is required for stability
*** C3 is recommended for EMC susceptibility
* C1 is required if the regulator is far from the power source filter
