THREE–TERMINAL LOW

CURRENT NEGATIVE FIXED

VOLTAGE REGULATORS

The MC79L00, A Series negative voltage regulators are inexpensive,

easy–to–use devices suitable for numerous applications requiring up to100

mA. Like the higher powered MC7900 Series negative regulators, this series

features thermal shutdown and current limiting, making them remarkably

rugged. In most applications, no external components are required for

operation.

The MC79L00 devices are useful for on–card regulation or any other

application where a regulated negative voltage at a modest current level is

needed. These regulators offer substantial advantage over the common

resistor/zener diode approach.

* 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 modifica-

tion decreases package thermal resistance and

increases power dissipation capability when

appropriately mounted on a printed circuit board.

SOP–8 conforms to all external dimensions of the

standard SO–8 package.

APPLICATIONS INFORMATION

Design Considerations

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 regulator’s input terminals. Normally good construction

techniques should be used to minimize ground loops and

lead resistance drops since the regulator has no external

sense lead. Bypassing the output is also recommended.

The MC79L00, A Series of fixed voltage regulators are

designed with Thermal Overload Protections that shuts down

the circuit when subjected to an excessive power overload

condition, Internal Short Circuit Protection that limits the

maximum current the circuit will pass.

In many low current applications, compensation

capacitors are not required. However, it is recommended that

the regulator input be bypassed with a capacitor if the

regulator is connected to the power supply filter with long wire

length, or if the output load capacitance is large. An input

A common ground is required between the input and the output
