NOTES:
Note 1:
Maximum positive supply voltage of 20V must be of limited duration (<100ms) and duty cycle of less than 1%. The
maximum continuous supply voltage is 16V.
Note 2:
Full load current (I
FL
) is defined as 5A.
Note 3:

+1V. For example, use V
IN
= 4.3V for a 3.3V regulator. Employ pulse-testing procedures to minimize
temperature rise.
Note 4
Ground pin current is the regulator quiescent current. The total current drawn from the source is the sum of the load current
plus the ground pin current.
Note 5:
Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range.
Note 6:
Thermal regulation is defined as the change in output voltage at time T after a change in power dissipation is applied,
excluding load / line regulation effects. Specifications for a 200mA load pulse as V
IN
= 20V (a 4W pulse) for t = 10ms.

Note 8:
Comparator threshold is expressed in terms of a voltage differential at the Adjust terminal below the nominal reference
voltage measured 6V input. To express these thresholds in terms of output voltage change, multiply the error amplifier gain =
V
/V
= (R1 + R2)/R2. For example, at a programmable output voltage of 5V, the Error output is guaranteed to go low when
the output drops by 95mVx 5V/ 1.240V = 383mV. Threshold remain constant as a percent of V

dropout warning occurring at typically 5% below nominal, 7.7% guaranteed.
