(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 and12V 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.

Consult LTC Marketing for parts specified with wider operating temperature ranges.
