1 MC7800, MC7800, MC7800E, NCV Positive Voltage Regulators These voltage regulators are monolithic integrated circuits designed as fixedvoltage regulators for a wide variety of applications including local, oncard regulation. These regulators employ internal current limiting, thermal shutdown, and safearea compensation. With adequate heatsinking they can deliver output currents in excess of 1.0. lthough designed primarily as a fixed voltage regulator, these devices can be used with external components to obtain adjustable voltages and currents. Features Output Current in Excess of 1.0 No External Components Required Internal Thermal Overload Protection Internal Short Circuit Current Limiting Output Transistor Saferea Compensation Output Voltage Offered in 1.5%, 2% and 4% Tolerance vailable in Surface Mount D 2 PK3, DPK3 and Standard 3Lead Transistor Packages NCV Prefix for utomotive and Other pplications Requiring Unique Site and Control Change Requirements; ECQ100 Qualified and PPP Capable These are PbFree Devices Pin 1.

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. * C in is required if regulator is located an appreciable distance from power supply filter. ** C O is not needed for stability; however, it does improve transient response.

21 PPLICTIONS INFORMTION Design Considerations The MC7800 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 Saferea 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. n input bypass capacitor should be selected to provide good highfrequency characteristics to insure stable operation under all load conditions 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 regulators 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. Input MC F R The MC7800 regulators can also be used as a current source when connected as above. In order to minimize dissipation the MC7805C is chosen in this application. Resistor R determines the current as follows: I O Constant Current to Grounded Load Input 0.33 F MC k MC1741G 10 k Output 0.1 F I 5.0 V O R I B I B 3.2 m over line and load changes. For example, a 1.0 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. Figure 9. Current Regulator V O = 7.0 V to 20 V V IN = V O 2.0 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. Figure 10. djustable Output Regulator R Source MJ2955 or Equiv. R Source R SC MJ2955 or Equiv.

The MC7800 series can be current boosted with a PNP transistor. The MJ2955 provides current to 5.0. 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. XX = 2 digits of type number indicating voltage. The circuit of Figure 11 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 four-ampere plastic power transistor is specified. Figure 11.

23 DEFINITIONS Line Regulation The change in output voltage for a change in the input voltage. 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 The maximum total device dissipation for which the regulator will operate within specifications. Quiescent 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.
