Shutdown Operation
The demo board includes a pull-up resistor, R3, to enable the device once V
IN
has exceeded 1.8V (typ).
Use the EN post to disable the device by pulling this node to GND. A logic signal may be applied, to the
post, to test startup and shutdown of the device.

Adjusting the Output Voltage
The output voltage can be changed from 1.8V to another voltage by adjusting the feedback resistors using
the following equation:
the following equation:
V
OUT
= V
FB
(1 + (R1/R2))

Where V
FB
is 0.6V.
