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.

• Wide Range of Available, Fixed Output Voltages

• Low Cost

• Internal Short Circuit Current Limiting

• Internal Thermal Overload Protection

• No External Components Required

• Complementary Negative Regulators Offered (MC79L00A Series)

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.

CASE 751

*SOP–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. SOP–8 conforms to all exter-

nal dimensions of the standard SO–8 package.

MC78L00A Series, NCV78L05A APPLICATIONS INFORMATION Design Considerations input bypass capacitor should be selected to provide good high–frequency characteristics to insure stable operation under all load conditions. A 0.33 µF or larger tantalum, mylar, or other capacitor 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.
