MC78L00A Series,
NCV78L00A
100 mA Positive Voltage
Regulators
The MC78L00A Series of positive voltage regulators are
inexpensive, easy−to−use devices suitable for a multitude of
applications that require a regulated supply of up to 100 mA. Like
their higher powered MC7800 and MC78M00 Series cousins, these
regulators feature internal current limiting and thermal shutdown
making them remarkably rugged. No external components are
required with the MC78L00 devices in many applications.
These devices offer a substantial performance advantage over the
traditional zener diode−resistor combination, as output impedance
and quiescent current are substantially reduced.

*SOIC−8 is an internally modified SO−8 package. Pins
2, 3, 6, and 7 are electrically common to the die attach
flag. This internal lead frame modification decreases
package thermal resistance and increases power
dissipation capability when appropriately mounted on
a printed circuit board. SOIC−8 conforms to all ex-
ternal dimensions of the standard SO−8 package.

is not defined. SOIC 8 lead and TO-92 packages that do not have a heat sink like other packages
may have. This is the reason that a Theta JC is never specified. A little heat transfer will occur through the package but since it is plastic, it is
minimal. The majority of the heat that is transferred is through the leads where they connect to the circuit board.
