Input Supply
To maintain output regulation the input voltage can vary from 10V to 100V with respect to the GND pin. It is
recommended to connect a 1µF capacitor to GND.
GND
Power Ground
This pin should be tied to the system ground.
V
OUT
Voltage Output
Outputs a regulated 5V. It is recommended to connect a 10µF capacitor to GND. Minimum of 10µA must be
drawn from V
OUT
to maintain regulation. The pin can be pulled high to a maximum of 11V with respect to
ground.
