Electrical Characteristics
(Continued)
Note 1:
“Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur. “Operating Ratings” indicate conditions for which the device is
functional, but do not guarantee specific performance limits. “Electrical Characteristics”state DC andAC electrical specifications under particular test conditions which
guarantee specific performance limits. This assumes that the device is within the Operating Ratings. Specifications are not guaranteed for parameters where no limit
is given, however, the typical value is a good indication of device performance.
Note 2:
Human body model, 150 pFcapacitor discharged through a 1.5 k
resistor.
Note 3:
If either control input is left open circuited the regulators will turn OFF.
Note 4:
The input quiescent current will increase when the regulators are in dropout conditions. The amount of additional input current is a direct function of the to
a load current on both outputs. The peak increase in current is limited to 50% of the total load current.
Note 5:
The dropout voltage specifications actually indicate the saturation voltage of the PNP power transistors used in each regulator. Over the full load current and
temperature ranges the Main regulator will output at least 4.5V and the External Supply regulator at lease 4.7V with an input voltage of only 5.5V
Note 6:
The ON/OFF input is internally clamped to a 7V zener diode through a 1K
resistor.
