www.DataSheet4U.com MC7800, MC7800A, NCV7805 1.0 A Positive Voltage Regulators These voltage regulators are monolithic integrated circuits designed as fixed−voltage regulators for a wide variety of applications including local, on−card regulation. These regulators employ internal current limiting, thermal shutdown, and safe−area compensation. With adequate heatsinking they can deliver output currents in excess of 1.0 A. Although designed primarily as a fixed voltage regulator, these devices can be used with external components to obtain adjustable voltages and currents. Output Current in Excess of 1.0 A No External Components Required Internal Thermal Overload Protection Internal Short Circuit Current Limiting Output Transistor Safe−Area Compensation Output Voltage Offered in 2% and 4% Tolerance Available in Surface Mount D2PAK−3, DPAK−3 and Standard 3−Lead Transistor Packages NCV Prefix for Automotive and Other Applications Requiring Site and Control Changes Pb−Free Packages are Available MAXIMUM RATINGS (TA = 25°C, unless otherwise noted) Value Rating Input Voltage Power Dissipation Thermal Resistance, Junction−to−Ambient Thermal Resistance, Junction−to−Case Storage Junction Temperature Range Operating Junction Temperature (5.0 − 18 V) (24 V) Symbol VI PD RqJA RqJC Tstg TJ 369C 221A 35 40 Internally Limited 92 5.0 65 5.0 −65 to +150 +150 Figure 14 5.0 936 Vdc W °C/W °C/W °C °C Unit http://onsemi.com TO−220−3 T SUFFIX CASE 221A 1 Heatsink surface connect...
