Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical specifications do not
apply when operating the device outside of its rated operating conditions. The maximum allowable power dissipation is a
function of the maximum junction temperature, T

regulator will go into thermal shutdown. The
mounted on a PC board (see “Thermal Considerations” section for further details).
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 100mA. 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 100mA load pulse at V
