(1) When used in dual-supply systems where the regulator load is returned to a negative supply, the output voltage must be diode-clamped
to ground.
(2) Output voltage temperature coefficient is defined as the worst-case voltage change divided by the total temperature range.
(3) Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested separately for load
regulation in the load ranges 0.1 mA to 1 mA and 1 mAto 250 mA. Changes in output voltage due to heating effects are covered by the
thermal regulation specification.
(4) Dropout voltage is defined as the input-to-output differential at which the output voltage drops 100 mV below the value measured with a
1-V differential.
(5) GND pin current is the regulator quiescent current. The total current drawn from the source is the sum of the load current plus the GND
pin current.
