Note 2: Full load current (I
Note 3: Dropout voltage is defined (V
Note 4: V
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
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
guaranteed to go low when the output drops by 95mVx 5V/ 1.240V = 383mV. Threshold remain constant as a percent of
V
