characterization testing. Signal levels between 0.8V and 2.0V with rise and fall times measured between 10% and 90%
of maximum and minimum values. Not production tested. Additional timing specifications were fully characterized and
specified that are not production tested.

temperature range. V
Load regulation is measured at a constant junction temperature using low duty cycle pulse testing. Changes in output
voltage due to heating effects are determined using thermal regulation specification TCV
Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its measured
value with an applied input voltage of V
