APPLICATIONS INFORMATION
DESIGNCONSIDERATIONS
The L78M00AB Series of fixed voltage regulators
are designed withThermal Overload Protection that
shuts down the circuit when subjected to an
excessive
power
overload
Short-Circuit Protection that limits the maximum
current the circuit will pass, and Output Transistor
Safe-Area Compensation that reduces the output
short-circuit as the voltage across the pass
transistor is increased.
In many low current applications, compensation
capacitors
are not required.
recommended that theregulator input be bypassed
condition,
Internal
However,
it
is
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
μ
F or
larger tantalum, mylar,or othercapacitor 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.
construction techniques should beusedtominimize
ground loops and lead resistance drops since the
regulator has no externalsense lead.
