Electrical Characteristics LM3480-3.3, LM3480-5.0 (continued)

Typicals and limits appearing in normal type apply for TA = TJ = 25°C. Limits appearing in boldface type apply over the entire

junction temperature range for operation,

−40 to +125°C.

(1)

A typical is the center of characterization data taken with TA = TJ = 25°C. Typicals are not ensured.

(2)

All limits are ensured. All electrical characteristics having room-temperature limits are tested during production with TA = TJ = 25°C. All

hot and cold limits are ensured by correlating the electrical characteristics to process and temperature variations and applying statistical

process control.

(3)

All voltages except dropout are with respect to the voltage at the GND pin.
