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
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
Ground current is specified for normal operation as well as “drop-out” operation.
The device’s shutdown pin includes a typical 2-MW internal pull-down resistor connected to ground.
