(1) Pulse-testing techniques maintain the junction temperature as close to the ambient temperature as possible. Thermal effects must be
taken into account separately.
(2) Input voltage regulation is expressed here as the percentage change in output voltage per 1-V change at the input
(3) Due to the dropout voltage and output current-limiting characteristics of this device, output current is limited to less than 700 mA at
input-to-output voltage differentials of less than 25 V.
