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 connected to Pin 2. 3 Pin 1.

The input voltage must remain typically 2.0 V above the output voltage even during the low point on the input ripple voltage. XX, These two digits of the type number indicate nominal voltage. * Cin is required if regulator is located an appreciable distance from power supply filter. ** CO is not needed for stability; however, it does improve transient response. Values of less than 0.1 mF could cause instability. Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected. *This device series contains ESD protection and exceeds the following tests: Human Body Model 2000 V per MIL_STD_883, Method 3015. Machine Model Method 200 V. ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 22 of this data sheet.
