A pullup resistor at EN may be added to ensure that the device starts without
a signal applied to the EN-pin. Connect EN to GND to disable the device. In
this state the supply current of the IC decreases to < 0.01

is used with the pullup resistor, R1, be aware that this resistor draws more
current than the device itself. For operating the device in low current mode, this
resistor has to be removed.

An additional GND-pin has been added for your convenience.
C4 to C6 are 0805-size SMD-footprints. These parts are not necessary for
operation and have only been added for test purposes. They can be used as
test points or to easily increase the value of a capacitor by adding an other one
in parallel.
