Regulator Output Current Shutdown
Note 1 : Output or reference voltage temperature coefficients defined as the worst case voltage change divided by the
total temperature range.
Note 2 : Regulations is measured at constant junction temperature, using pulse testing with a low duty cycle.
Changes in output voltage due to heating effects are covered under the specification for thermal regulation.
Note 3 : Line regulation is tested at 150℃ for IL = 1mA. For IL = 100㎂ and TJ = 125℃, line regulation is guaranteed by
value measured at 1V differential.
Note 4 : 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.
Note 5 : Ground pin current is the regulator quiescent current. The Total current drawn from the source is the sum of the
ground pin current and output load current.
Note 6 : Thermal Regulation is the change in output voltage at a time T after a change in power dissipation, excluding
load or line regulation effects. Specifications are for a 50mA load puls (1.25W) for T = 10ms
