Notes:
The Bold specifications apply to the full operating temperature range.
Note 1: Maximum positive supply voltage of 60V must be of limited duration (<100msec) and duty cycle.) The maximum continuous supply voltage is 16V.
Note 2: Full load current (I

) is defined as 1.5A for the

IN
= 4.3V for a3.3V regulator. Employ pulse-testing procedures to minimize temperature rise.
Note 5: Ground pin current is the regulator quiescent current. The total current drawn from the source is the sum of the load current to the ground current.
Note 6: Output voltage temperature coefficient is defined as the worst case voltage changed divided by the total temperature range.
Note 7: Thermal regulation is defined as the change in the output voltage at a time T after a change in power dissipation is applied, excluding load or line regulation
effects. Specifications are for a 200mA load pulse as V

= 20V (a 4W pulse) for T = 10ms.

Note 9: Comparator threshold is expressed in terms of a voltage differential at the Adjust terminal below the nominal reference voltage measured a 6V input. To
express these thresholds in terms of output voltage change, multiply the error amplifier gain = V
