MC7800, MC7800A, LM340, LM340A Series Three-Terminal Positive Voltage Regulators
These voltage regulators are monolithic integrated circuits designed as fixed-voltage regulators for a wide variety of applications including local, on-card regulation. These regulators employ internal current limiting, thermal shutdown, and safe-area compensation. With adequate heatsinking they can deliver output currents in excess of 1.0 A. Although designed primarily as a fixed voltage regulator, these devices can be used with external components to obtain adjustable voltages and currents. * Output Current in Excess of 1.0 A * No External Components Required * Internal Thermal Overload Protection * Internal Short Circuit Current Limiting * Output Transistor Safe-Area Compensation * Output Voltage Offered in 2% and 4% Tolerance * Available in Surface Mount D2PAK, DPAK and Standard 3-Lead Transistor Packages

A common ground is required between the input and the output voltages. 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. * Cin is required if regulator is located an appreciable distance from power supply filter. ** CO is not needed for stability; however, it does improve transient response. Values of less than 0.1 F could cause instability.

APPLICATIONS INFORMATION wire lengths, or if the output load capacitance is large. An input bypass capacitor should be selected to provide good The MC7800 Series of fixed voltage regulators are high-frequency characteristics to insure stable operation designed with Thermal Overload Protection that shuts down under all load conditions. A 0.33 F or larger tantalum, the circuit when subjected to an excessive power overload mylar, or other capacitor having low internal impedance at condition, Internal Short Circuit Protection that limits the high frequencies should be chosen. The bypass capacitor maximum current the circuit will pass, and Output Transistor should be mounted with the shortest possible leads directly Safe-Area Compensation that reduces the output short circuit across the regulators input terminals. Normally good current as the voltage across the pass transistor is increased. construction techniques should be used to minimize ground In many low current applications, compensation loops and lead resistance drops since the regulator has no capacitors are not required. However, it is recommended external sense lead. that the regulator input be bypassed with a capacitor if the regulator is connected to the power supply filter with long

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 + 5.0 V ) I B O R IB ^ 3.2 mA over line and load changes. For example, a 1.0 A 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.

VO = 7.0 V to 20 V VIN = VO 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.

The circuit of Figure 10 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 four-ampere plastic power transistor is specified. Output

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.

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.
