... Regulation is measured at constant junction temperature, using pulse testing with a low duty cycle. Changes in output voltage due to heating effects are covered under the specification for thermal regulation. 10. Line regulation for the RC2951 is tested at 150 C for I by design to 0.2%. See Typical Performance Characteristics for line regulation versus temperature and load current. ...

... When setting the output voltage of the RC2951 versions with external resistors, a minimum load recommended tantalum or aluminum electrolytic capacitor should be placed from the RC2951 input to ground if there is more than 10 inches of wire between the input and the AC filter capacitor battery is used as the input. ...
