These applications include on-card regulation for elimination of noise and distribution problems associated with single-point regulation.Each of these regulators can deliver up to500mA of output current.The internal current-limiting and thermal-shutdown features of these regulators essentially make them immune to overload.In addition to use as fixed-voltage regulators,these devices can be used with external components to obtain adjustable output voltages and currents and also as the power-pass element in precision regulators.Please be aware that an important notice concerning availability,standard warranty,and use in critical applications of TexasInstruments semiconductor products and disclaimers thereto appears at the end of this data sheet.PowerFLEX,PowerPAD are

MC78M00, MC78M00A Series500 mA Positive Voltage RegulatorsThe MC78M00/MC78M00A Series positive voltage regulators are identical to the popular MC7800 Series devices, except that they are specified for only half the output current. Like the MC7800 devices,the MC78M00 three-terminal regulators are intended for local,on-card voltage regulation.Internal current limiting, thermal shutdown circuitry and safe-area compensation for the internal pass transistor combine to make these devices remarkably rugged under most operating conditions.Maximum output current, with adequate heatsinking is 500 mA.Features•ăNo External Components Required •ăInternal Thermal Overload Protection •ăInternal Short Circuit Current Limiting •ăOutput Transistor Safe-Area Compensation •ăMC78M00A High Accuracy (±2%)Available for 5.0 V , 8.0 V , 12 V and 15 V •ăPb-Free Packages are Available*Figure 1.

The measurement is made under conditions of low dissipation or by using pulse techniques such that the average chip temperature is not significantly affected.Load Regulation - The change in output voltage for a change in load current at constant chip temperature.Maximum Power Dissipation - T he maximum total device dissipation for which the regulator will operate within specifications.Input Bias Current - That part of the input current that is not delivered to the load.Output Noise Voltage - T he rms AC voltage at the output, with constant load and no input ripple, measured over a specified frequency range.Long Term Stability - Output voltage stability under accelerated life test conditions with the maximum rated voltage listed in the devices' electrical characteristics and maximum power dissipation.Figure 3.

However, it is recommended that the regulator input be bypassed with a capacitor if theregulator is connected to the power supply filter with long wire lengths, or if the output load capacitance is large. An input bypass capacitor should be selected to provide good high frequency characteristics to insure stable operation under all load conditions. A 0.33 m F or larger tantalum,mylar, or other capacitor having low internal impedance at high frequencies should be chosen. The bypass capacitor should be mounted with the shortest possible leads directly across the regulator's input terminals. Normally good construction techniques should be used to minimize ground loops and lead resistance drops since the regulator has no external sense lead.m FThe MC78M00 series can be current boosted with a PNP transistor. The MJ2955 provides current to 5.0 A. Resistor R in conjunction with the V BE of the PNP determines when the pass transistor begins conducting; this circuit is not short circuit proof. Input-output differential voltage minimum is increased by V BE of the pass transistor.InputThe circuit of Figure 12 can be modified to provide supply protection against short circuits by adding a short circuit sense resistor, R sc ,and an additional PNP transistor. The current sensing PNP must be able to handle the short circuit current of the three-terminal regulator .Therefore, a 4.0 A plastic power transistor is specified.XX = 2 digits of type number indicating voltage.Figure 12.
