MC78M00, MC78M00A, NCV78M00 Series 500 mA 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. http://onsemi.com MARKING DIAGRAMS TO−220 T SUFFIX CASE 221AB Heatsink surface connected to Pin 2.

An input bypass capacitor should be selected to provide good high frequency characteristics to insure stable operation under all load conditions. A 0.33 mF 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/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 VO, 7.0 V to 20 V Vin-Vout ≥ 2.0 V MC78M05C Input 0.33 mF R IO Constant Current to Grounded Load Output MC78M05C Input 7 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 = 0.33 mF 6 * + 1.0 k 2 0.1 mF 3 10 k 4 MC1741 5.0 V + IIB R IIB = 1.5 mA over line and load changes. 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. For example, a 500 mA current source would require R to be a 10W, 10 W resistor and the output voltage compliance would be the input voltage less 7.0 V. Figure 10. Current Regulator Figure 11. Adjustable Output Regulator MJ2955 or Equiv. RSC Input MJ2955 or Equiv. Input R MC78MXXC Output R 1.0 mF 1.0 mF 2N6049 or Equiv. MC78MXXC 1.0 mF Output 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 12 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. Figure 12.
