Regulation is measured at a constant junction temperature using low duty cycle pulse testing. Load regulation is tested over a load range from
0.1mA to the maximum specified output current. Changes in output voltage due to heating effects are covered by the thermal regulation specifica-
Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value measured at a 1V differen-
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 current pulse equal to ILMAX at VIN = 6V for T = 10 msec.
The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable junction temperature and the
thermal resistance from junction-to-air (i.e., TA, TJ, θJA). Exceeding the maximum allowable power dissipation causes the device to initiate
thermal shutdown. Please see Section 4.0 Thermal Considerations for more details.
