Note 4:
May exceed the input supply voltage.
Note 5:
Output or reference voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range.
Note 6:
Output voltage load regulation is measured at constant junction temperature using low duty cycle pulse testing. Two separate tests are performed, one for
the load current range of 100 μA to 1 mA and one for the 1 mA to 500 mA range. Changes in output voltage due to heating effects are covered by the thermal regu-
lation specification.
Note 7:
Dropout voltage is defined as the input to output differential at which the output voltage drops 100 mV below the value measured with a 1V differential. At
very low values of programmed output voltage, the input voltage minimum of 2V
(2.3V over temperature)
must be observed.
Note 8:
Ground pin current is the regulator quiescent current. The total current drawn from the source is the sum of the ground pin current, output load current, and
current through the external resistive divider (if used).
Note 9:
Dropout detection comparator threshold voltages are expressed in terms of a voltage differential measured at the Feedback terminal below the nominal ref-
erence voltage, which is the reference voltage measured with V
= V
(NOM) + 1V. To express these thresholds in terms of output voltage change, multiply by the
error amplifier gain which is V

REF
= (R1 + R2)/R2 (see Basic Application Circuit).
Note 10:
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 400 mA load pulse at V

Note 14:

are guaranteed via correlation using standard Statistical Quality
Control (SQC) methods. All limits are used to calculate Average Outgoing Quality Level.
