The algebraic convention whereby the most negative value is a minimum and the most positive a maximum.
Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing. Typical values for dropout voltage at V
OUT
V
= 3.3 V, while typical values for dropout voltage at V
< 2 V are measured at V
= 1.8 V.
Dropout voltage is defined as the input to output differential voltage at which the output voltage drops 2% below the output voltage measured with a 1-V
differential, provided that V
does not not drop below 2.0 V. When V
OUT(nom)
is less than 2.0 V, the output will be in regulation when 2.0 V
–
V
OUT(nom)
is
greater than the dropout voltage specified.
The device
’
s shutdown pin includes a typical 6-M internal pull-down resistor connected to ground.
V
is defined as the output voltage of the DUT at 1 mA.
The Error Output (Low) function is guaranteed for V
