| Solved by TM SP78XX 3-Terminal Positive Regulators TO-220 Package Features Output Current up to 1.0A Fixed Output Voltages of 5V and 12V Output Voltage Tolerances of 5% over the Full Temperature Range Internal Short Circuit Current-limiting Internal Thermal Overload Protection Available in Lead Free, RoHS Compliant Packages 3 2 OUTPUT GND INPUT applications Consumer Electronics Microprocessor Power Supply Mother Board I/O Power Supply general Description The SP78XX series are monolithic integrated circuits designed as fixed-voltage regulators for a wide variety of applications including local, on-card regulation. This series of regulators are complete with internal current limiting, thermal shutdown protection, and safe-area compensation which make them virtually immune from output overload. If adequate heat sinking are provided, these regulators can deliver output currents up to 1.0A. The SP78XX series are available in two standard plastic packages: TO-220 and TO-252.
