The MC78L00, A 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.

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 external dimensions of the

standard SO–8 package.
