* Although the devices’ maximum operating voltage is limited (20V for the 5V device, and 25V for the 12V and adjustable 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 5V and 12V devices operating at input-output voltage differentials >15V, a minimum external load of 5mA is required to

maintain regulation.
