Order this document by MCT7800/D ThreeĆTerminal 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 fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents. • Output Current in Excess of 1.0 A MCT7800 Series THREE-TERMINAL POSITIVE FIXED VOLTAGE REGULATORS • • • • • • No External Components Required Internal Thermal Overload Protection Internal Short Circuit Current Limiting Output Transistor Safe-Area Compensation Output Voltage Offered with a 4% Tolerance Available in Surface Mount D2PAK and Standard 3-Lead Transistor Packages T SUFFIX PLASTIC PACKAGE CASE 221A Heatsink surface connected to Pin 2. 1 2 3 Pin 1.

Because the MCT device originates from different source material, there may be subtle differences in typical parameter values or characteristic curves. Due to the diversity of potential applications, Motorola can not assure identical performance in all circuits. Motorola recommends that the customer qualify the MCT-prefixed device in each potential application. Input Heatsink surface (shown as terminal 4 in case outline drawing) is connected to Pin 2. STANDARD APPLICATION MCT78XX CO*- Output DEVICE TYPE/NOMINAL OUTPUT VOLTAGE MCT7805 MCT7806 MCT7808 MCT7809 5.0 V 6.0 V 8.0 V 9.0 V MCT7812 MCT7815 MCT7818 MCT7824 12 V 15 V 18 V 24 V Cin- 0.33 µF 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. *- Some CO is recommended for stability; it does improve transient response. Values less than 0.1 µF could cause instability. © Motorola, Inc. 1994 Rev 3 ORDERING INFORMATION Device MCT78XXBD2T MCT78XXBT 4% MCT78XXCD2T MCT78XXCT XX indicates nominal voltage.
