lm9073 National Semiconductor Corporation, lm9073 Datasheet - Page 5

• Manufacturer Part Number: lm9073
• Description: Dual High Current Low-dropout System Regulator
• Manufacturer: National Semiconductor Corporation

Electrical Characteristics
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 1KΩ resistor.
