100ma low dropout voltage regulators LM2930/1 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 i l =1ma. for i l =100ua and t j =125 , line regulation is guaranteed by design to 0.2%. 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 pulse (1.25w) for t=10ms. note 7 : v ref v o (v in -1v), 2.3v v in 30v, 100 ? i l 100 ? , t j t jmax note 8 : v shutdown 2v, v in 26v, v o =0, feed-back pin tied to -xx v tap. htc - 4 -
