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
common resistor/zener diode approach

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.
*C in is required if regulator is located an
*appreciable
distance from power supply filter.
**C O is not needed for stability; however, it does
*improve
transient response.
