1 General Description The series are three terminal positive regulators with several fixed output voltages. These regulators can provide local on card regulation, eliminating the distribution problems associated with single point regulation. The can be used in logic systems, instrumentation, HiFi, and other solid state electronic equipment. When used as a Zener diode/resistor combination replacement, the usually results an effective output impedance improvement of two orders of magnitude, and lower quiescent current. With adequate heat sinking the can deliver 100mA 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. Features Output Current up to 100mA Fixed Output Voltages of 5V, 8V, 9V and 12V Output Voltage Tolerances of ±5% over the Full Temperature Range Internal Short Circuit Current-limiting Internal Thermal Overload Protection No External Components Applications High Efficiency Linear Regulator Post Regulation for Switching Supply Microprocessor Power Supply Mother Board I/O Power Supply The are available in the plastic TO-92 (bulk or ammo packing), SOT-223 and SOT-89 packages.
