† _{Pulse-testing techniques maintain the junction temperature as close to the ambient temperature as possible. Thermal effects must be taken into}
account separately.
‡ _{Input voltage regulation is expressed here as the percentage change in output voltage per 1-V change at the input.}
NOTE 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.
