general Description
The SP78LXX series are three terminal positive regulators with several fixed output voltages. These regulators can provide local on-card regulation, eliminating distribution problems associated with single point regulation. The SP78LXX can be used in logic systems, instrumentation, HiFi, and other solid state electronic equipment. When used as a Zener diode/resistor combination replacement, the SP78LXX usually results an effective output impedance improvement of two orders of magnitude, and lower quiescent current. With adequate heat sinking the SP78LXX can deliver 100 mA output current. Current limiting is included to limit the peak output current to a safe value. Thermal protection is also provided. If internal power dissipation becomes too high for the heat sinking provided, the thermal shutdown circuit takes over preventing the IC from overheating. The SP78LXX are available in the plastic TO-92, NSOIC-8, SOT-223 and SOT-89 packages.
