NOTES:
Note 1: Dropout voltage is defined as the input to output differential when the output voltage drops to 99% of its nominal value.
Note 2: V IN = V OUT (NOMINAL) +1V. For example, use V IN = 4.3V for a 3.3V regulator. Employ pulse-testing procedures to minimize temperature rise.
Note 3: 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 4: 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.
Note 5: 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 = 38mV. Thresholds
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 6: V EN ≤ 0.8V and V IN ≤ 16V, V OUT = 0.
Note 7: Maximum positive supply voltage of 20V must be of limited duration (<100m_) < 1%. The maximum continuous supply voltage is 16V.
Note 8: V REF ≤ V OUT ≤ (V IN -1), 2.5V≤V IN ≤ 16V, 10mA ≤ I L ≤ I FL , T J < T JMAX .
