100 mA Negative Voltage
Regulators
The STC79L00, A Series negative voltage regulators are
inexpensive, easy−to−use devices suitable for numerous applications
requiring up to 100 mA. Like the higher powered STC7900 Series
negative regulators, this series features thermal shutdown and current
limiting, making them remarkably rugged. In most applications, no
external components are required for operation.
The STC79L00 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.
