† 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.
