DESCRIPTION
If adequate heat sinking is provided, they can deliver over 1A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents. 1 2 TO-3 D2PAK TO-220 ISOWATT220 BLOCK DIAGRAM November 1999 1/25 L7800 ABSOLUTE MAXIMUM RATINGS
