Voltage Regulators – Positive 1.0 A MC7800, MC7800A, MC7800AE, NCV7800 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 .

Voltage Regulators – Positive 1.0 A MC7800, MC7800A, MC7800AE, NCV7800 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. Features • 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 1.5%, 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 Unique Site and Control Change Requirements; AEC−Q100 Qualified and PPAP Capable • These are Pb−Free Devices MAXIMUM RATINGS (TA = 25°C, unless otherwise noted) Value Unit Rating Symbol 369C 221A 936 Input Voltage (5.0 − 18 V) VI (24 V) 35 Vdc 40 Power Dissipation Thermal Resistance, Junction−to−Ambient PD RqJA Internally Limited W 92 65 Figure °C/W 15 Thermal Resistance, Junction−to−Case RqJC 5.0 5.0 5.0 °C/W Storage Junction Temperature Tstg Range −65 to +150 °C Operating Junction Temperature TJ +150 °C Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality should not be assumed, 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. DATA SHEET www.onsemi.com 12 3 TO−220 T SUFFIX CASE 221AB Heatsink surface connected to Pin 2. Pin 1. Input D2PAK−3 2. Ground D2T SUFFIX 1 3. Output CASE 936 3 Heatsink surface (shown as terminal 4 in case outline drawing) is connected to Pin 2. 4 12 3 DPAK−3 DT SUFFIX CASE 369C STANDARD APPLICATION Input Cin* 0.33 mF MC78XX Output CO** A common ground is required between the input and the output voltages. 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. ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 23 of this data sheet.
