DESCRIPTION
The L7800A series of three-terminal positive
regulators is available in TO-220 and D

PAK
packages and several fixed output voltages,
making it useful in a wide range of
applications.These regulators can provide local
on-card regulation, eliminating the distribution
problems associated with single point regulation.
Each type employs internal current limiting,
thermal shut-down and safe area protection,
making it essentially indestructible. If adequate
heat sinking is provided, they can deliver over 1A
output current. Although designed primarily as
fixed voltage regulators, these devices can be
used with external components to obtain
adjustablevoltages and currents.

APPLICATIONSINFORMATION
DESIGNCONSIDERATIONS
The L7800ASeriesof fixedvoltage regulatorsare
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
currentthe circuit will pass, and Output Transistor
Safe-AreaCompensation that reduces the output
short-circuit current as the voltage across the
passtransistoris 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 underall
load conditions. A 0.33µF or larger tantalum,
mylar, or other capacitor having low internal
impedanceat high frequenciesshould be chosen.
The bypasscapacitor should bemounted 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
sincethe regulatorhas no externalsense lead.

The addition of an operational amplifier allows
adjustmentto higher or intermediate values while
retaining regulation characteristics. The minimum
voltage obtainable with this arrangement is 2.0V
greaterthan the regulatorvoltage.
The circuit of figure 6 can be modified to provide
supply protectionagainst shortcircuit by adding a
short-circuit sense resistor, R
sc
, and an additional
PNP transistor. The current sensingPNP must be
able to handle the short-circuit current of the
three-terminal regulator. Therefore, a
