MC78M00, MC78M00A Series Three-Terminal Medium Current Positive Voltage Regulators
The 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. * No External Components Required * Internal Thermal Overload Protection * Internal Short Circuit Current Limiting * Output Transistor Safe-Area Compensation * MC78M00A High Accuracy (2%) Available for 5.0 V, 8.0 V, 12 V and 15 V

Load Regulation - The change in output voltage for a change in load current at constant chip temperature. Maximum Power Dissipation - The 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 - The 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.

APPLICATIONS INFORMATION
Design Considerations
The MC78M00/MC78M00A Series of fixed voltage regulators are designed with Thermal Overload Protection that shuts down the circuit when subjected to an excessive power overload condition, Internal Short Circuit Protection that limits the maximum current the circuit will pass, and Output Transistor Safe-Area Compensation that reduces the output short circuit current as the voltage across the pass transistor is increased. In many low current applications, compensation capacitors are not required. However, it is recommended that the regulator input be bypassed with a capacitor if the
regulator 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 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.

The MC78M00 regulators can also be used as a current source when connected as above. In order to minimize dissipation the MC78M05C is chosen in this application. Resistor R determines the current as follows: IO = 5.0 V + IIB R

IIB = 1.5 mA over line and load changes. For example, a 500 mA current source would require R to be a 5.0 , 10 W resistor and the output voltage compliance would be the input voltage less 7.0 V. The addition of an operational amplifier allows adjustment to higher or intermediate values while retaining regulation characteristics. The minimum voltage obtainable with this arrangement is 2.0 V greater than the regulator voltage.

XX = 2 digits of type number indicating voltage. XX = 2 digits of type number indicating voltage. The MC78M00 series can be current boosted with a PNP transistor. The MJ2955 provides current to 5.0 A. Resistor R in conjunction with the VBE 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 VBE of the pass transistor. The circuit of Figure 11 can be modified to provide supply protection against short circuits by adding a short circuit sense resistor, Rsc, 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.
