† 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.
NOTES: 2. Since long-term drift cannot be measured on the individual devices prior to shipment, this specification is not intended to be a
guarantee or warranty. It is an engineering estimate of the average drift to be expected from lot to lot.
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.
