Description

The GM78L00 series in positive voltage regulators are low-

cost devices providing a simple solution for a wide variety

of applications, which requires a regulated supply of up to

100mA.

These virtually indestructible positive voltage regulators

are protected by thermal shutdown and internal current-

limiting. Most applications require no external components.

The GM78L00 is very versatile. To use them as fixed volt-

age regulators in a wide range of applications, including

both local and on-card regulation for elimination of noise

and distribution problems associated with single-point regu-

lation. They can also be used with power pass elements to

make high current voltage regulators.

The GM78L00 offers impressive performance advantages

over old-fashioned zener diode-resistor combinations, pro-

viding lower output impedance and reduced quiescent cur-

A common ground is required between the input and the output voltages. The

input voltage must remain typically 2.0V above, the output voltage even during

the low point on the input ripple voltage.
