Exceeding the absolute maximum rating may damage the device.
The device is not guaranteed to function outside its operating rating.

. Exceeding the maximum

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 range from 0.1mA to 150mA. Changes in output voltage due to heating effects are covered by the thermal regulation
specification.
Dropout Voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value measured
at 1V differential.
Ground pin current is the regulator quiescent current plus pass transistor base current. The total current drawn from the supply is
the sum of the load current plus the ground pin current.
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 regulation effects. Specifications are for a 150mA load pulse at V
