These regulators can provide localon-card regulation, eliminating the distributionproblems associated with single point regulation.Eachtypeemploysinternalcurrentlimiting,thermal shut-down and safe area protection,making it essentially indestructible. If adequateheat sinking is provided, they can deliver over0.5A output current. Although designed primarilyas fixed voltage regulators, these devices can beusedwithexternalcomponentstoobtainadjustable voltage and currents.L78M00SERIESPOSITIVE VOLTAGE REGULATORSSCHEMATIC DIAGRAMTO-220DPAKTO-220FPIPAKL78M00 SERIES2/21ABSOLUTE MAXIMUM RATINGSAbsolute Maximum Ratings are those values beyond which damage to the device may occur.
