Note 1. Stresses beyond those listed under Absolute Maximum Ratingsmay cause permanent damage to the
device. These are stress ratings only, and functional operation of the device at these or any other conditions
beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
Note 2. Devices are ESD sensitive. Handling precaution recommended. The human body model is a 100pF capacitor
discharged through a 1.5K
resistor into each pin.
Note 3. The device is not guaranteed to function outside its operating conditions.
Note 4. Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its
nominal value measured at 0.7V differential.
Note 5. Regulation is measured at constant junction temperature by using a 20mS current pulse. Devices are tested
for load regulation in the load range from 10mA to 1.5A.
Note 6. Quiescent, or ground current, is the difference between input and output currents. It is defined by IQ = IIN - IOUT
under no load condition (IOUT = 0mA). The total current drawn from the supply is the sum of the load current
plus the ground pin current.
Note 7. Standby current is the input current drawn by a regulator when the output voltage is disabled by a shutdown
signal (VEN >1.8V ). It is measured with VIN = 5.5V.
