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.

• NCV Prefix for Automotive and Other Applications Requiring Site

*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

dissipationcapability when appropriately mounted on

a printed circuit board. SOIC−8 conforms to all exter-

nal dimensions of the standard SO−8 package.

Figure 2. 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.

*C is required if regulator is located an appreciable distance from power

supply filter.

** C is not needed for stability; however, it does improve transient response.
