Notes
Input voltage can vary from -0.3V to 60V with respect to GND; for VOUT regulated then 10V ≤ VIN ≤ 60V. It is
recommended to connect a 1µF capacitor to GND.
This pin should be tied to the system ground.
Outputs a regulated 8V when 10V ≤ VIN ≤ 60V. When VIN < 10V, then VOUT maximum = VIN – 1V.
The pin can be pulled high to a maximum of +13V with respect to GND, or +5V with respect to VIN,
whichever is lower. It is recommended to connect a 10µF capacitor to GND and a minimum of 10µA to be
drawn from VOUT to maintain regulation.
