Operating Ratings indicate conditions for which the device re- mains functional but do not guarantee specific performance limits. For guaranteed specifications and test conditions see the Electrical Characteristics. Note 2: Human body model, 150 pF capacitor discharged through a 1.5 k Ω 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 currents is a direct function of the total 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 both regulators will output at least 4.7V with an input voltage of only 5.5V. Note 6: The ON/OFF input is internally clamped to a 7V zener diode througha1k Ω resistor. www.national.com 3 |
