IL79LXX

1

The IL79LXX, A Series negative voltage regulators are inexpensive,

easy-to-use devices suitable for numerous applications requiring up to

100 mA. This series features thermal shutdown and current limiting,

making them remarkably rugged. In most applications, no external

components are required for operation.

The IL79LXX 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

A common ground is required between the input

and the output voltages. The input voltage must

remaintypically 2.0 V above the output voltage even

during the low point on the input ripple voltage.
