Description
The LM79L05A3 is an inexpensive, easy-to-use device suitable for numerous applications requiring up to 100mA. Like the higher powered LM7900E3 series negative
regulators, this device features thermal shutdown and current limiting, making it remarkably rugged. In most applications, no external components are
required for operation.
The LM79L05A3 device is useful for on-card regulation or any other application where a regulated negative voltage at a modest current level is needed. This
regulator offers substantial advantage over the common resistor/zener diode approach. No external components required Internal short circuit current limiting Internal thermal overload protection Low cost Complementary positive
regulators offered (LM78L05A3) Available in either ±3% or ±5% selection.
