1.0 A 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 D

3−Lead Transistor Packages

• NCV Prefix for Automotive and Other Applications Requiring Site

and Control Changes

• Pb−Free Packages are Available

Maximum ratings are those values beyond which device damage can occur.
Maximum ratings applied to the device are individual stress limit values (not
normal operating conditions) and are not valid simultaneously. If these limits are
exceeded, device functional operation is not implied, damage may occur and
reliability may be affected.

APPLICATIONS INFORMATION

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 c ircuit w ill p ass, a nd O utput Transistor
Safe−Area C ompensation t hat r educes t he o utput s hort c ircuit
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

Input

0.33 F

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:

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 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.

The MC7800 series can be current boosted with a PNP transistor. The
MJ2955 provides current to 5.0 A. Resistor R in conjunction with the V
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 addition of an operational amplifier allows adjustment to higher or

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

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.
