Note 9
Note 2: Full load current (I FL ) is defined as 3.0A.
Note 3: Dropout voltage is defined (V IN -V OUT ) when the output voltage drops to 99% of its nominal value.
Note 4: V IN =V OUT (nom)+1V. Use 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 change divided by the total temperature
range
Note 7: 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 OUT /V REF = (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 OUT as V OUT is varied, with the dropout warning occurring at typically 5% below nominal, 7.7% guaranteed.
Note 9: V EN ≤ 0.8V and V IN ≤ 16V, V OUT = 0.
