Output voltage temperature coefficient is defined as the worst-case voltage change divided by the total temperature range.
Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested for load regulation in the load
Dropout Voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value measured at 1V
Ground pin current is the regulator quiescent current plus pass transistor base current. The total current drawn from the supply is the sum of
Thermal regulation is defined as the change in output voltage at a time “t” after a change in power dissipation is applied, excluding load or line
