All characteristics are measured with a 0.1-
μ
F capacitor across the input and a 1-
μ
F capacitor across the output.
Input regulation is expressed here as the percentage change in output voltage per 1-V change at the input
Pulse testing techniques are used to maintain the junction temperature as close to the ambient temperature as possible.
Thermal effects must be taken into account separately.
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.

Use of an input bypass capacitor is recommended if regulator is far from filter capacitors.
Use of an output capacitor improves transient response but is optional.
