Note 1: Although the device’s maximum operating voltage is limited, (18V

for a 2.85V device, 20V for a 5V device, and 25V for adjustable and

12V devices) the devices are guaranteed to withstand transient input

voltages up to 30V. For input voltages greater than the maximum operating

input voltage some degradation of specifications will occur. For fixed

voltage devices operating at input/output voltage differentials greater than

15V, a minimum external load of 5mA is required to maintain regulation.
