Room = 25_C, Full = −40 to 85_C.
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.
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.
