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.
Features
•Output Current in Excess of 1.0 A

STANDARD APPLICATION
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.

Input
Cin*
0.33 mFCO**
Output
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 mF could cause instability.

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 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 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 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 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:
For example, a 1.0 A current source would require R to be a 5.0 W,
10 W resistor and the output voltage compliance would be the input
voltage less 7.0 V.
IB ^ 3.2 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.

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 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
four-ampere plastic power transistor is specified.

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.
