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
specification.
Dropout voltage is defined as the input to output differential at which the output voltage drops2% below its nominal value measured at a 1V
differential.
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 I
at V
= 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., T
, T
,
θ
). Exceeding the maximum allowable power dissipation causes the device to initiate
thermal shutdown. Please see Section 4.0 Thermal Considerations for more details.
