Input Decoupling (C1)
recommended and should be connected close to the
MC78LC00 package. Higher values and lower ESR will
improve the overall line transient response.
Output Decoupling (C2)
require any specific Equivalent Series Resistance (ESR) or
a minimum output current. Capacitors exhibiting ESRs
ranging from a few mW up to 3.0 W can thus safely be used.
The minimum decoupling value is 0.1 mF and can be
augmented to fulfill stringent load transient requirements.
The regulator accepts ceramic chip capacitors as well as
tantalum devices. Larger values improve noise rejection and
load regulation transient response.

chance to pick up noise or cause the regulator to
malfunction.

become necessary to provide some thermal relief. The
maximum power dissipation supported by the device is
dependent upon board design and layout. Mounting pad
configuration on the PCB, the board material, and also the
ambient temperature effect the rate of temperature rise for
the part. This is stating that when the MC78LC00 has good
thermal conductivity through the PCB, the junction
temperature will be relatively low with high power
dissipation applications.
