MC78T08

MC78T00 Series 3.0 A Positive Voltage Regulators This family of fixed voltage regulators are monolithic integrated circuits capable of driving loads in excess of 3.0 A. These three−terminal regulators employ internal current limiting, thermal shutdown, and safe−area compensation. Devices are available with improved specifications, including a 2% output voltage tolerance, on AC−suffix 5.0 V, 12 V and 15 V device types. Although designed primarily as a fixed voltage regulator, these devices can be used with external components to obtain adjustable voltages and currents. This series of devices can be used with a series−pass transistor to supply up to 15 A at the nominal output voltage. Output Current in Excess of 3.0 A Power Dissipation: 25 W No External Components Required Output Voltage Offered in 2% and 4% Tolerance* Thermal Regulation is Specified Internal Thermal Overload Protection Internal Short Circuit Current Limiting Output Transistor Safe−Area Compensation Pb−Free Packages are Available Input Cin* 0.33 mF MC78TXX Output CO** Figure 1. Simplified Application A common ground is required between the input and the output voltages. The input voltage must remain typically 2.2 V above the output voltage even during the low point on the input ripple voltage. XX these two digits of the type number indicate voltage. ** Cin is required if regulator is located an appreciable distance from power supply filter. ** (See Applications Information for details.) *...
