I O O For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions. Note 1: All characteristics are measured with a 0.1µF capacitor across the input and a 1µF capacitor across the output. Note 2: Input regulation is expressed here as the percentage change in output voltage per 1V change at the input. Note 3: Pulse testing techniques are used to mantain the junction temperature as close to the ambient temperature as possible. Thermal effects must be taken into account separately. Note 4: 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. A A MICROELECTRONICS GM317 Power Management 3- TERMINAL ADJUSTABLE REGULATOR
