(1) A typical is the center of characterization data taken with T
A
= T
J
= 25°C. Typicals are not ensured.
(2) All limits are ensured. All electrical characteristics having room-temperature limits are tested during production with T
A
= T
J
= 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.
