TIMING WAVEFORMS
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. 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
greater than the dropout voltage specified.
The device’s shutdown pin includes a typical 6-MW internal pull-down resistor connected to ground.
V
The Error Output (Low) function is guaranteed for V

= 3.3 V, while typical values for dropout voltage at V
is defined as the output voltage of the DUT at 1 mA.
