AZ78L08 Datasheet | BCD Semiconductor

Description Features Data Sheet AZ78LXX The AZ78LXX 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 AZ78LXX can be used in logic systems, instrumentation, Hi Fi, and other solid state electronic equipment. When used as a Zener diode/resistor bination replacement, the AZ78LXX usually results an effective output impedance improvement of two orders of magnitude, and lower quiescent current. - Output Current up to 100m A - 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 ponents Applications With adequate heat sinking the AZ78LXX can deliver - High Efficiency Linear Regulator 100m A 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 bees too high for the heat sinking - - - Post Regulation for Switching Supply Microprocessor Power Supply Mother Board I/O Power Supply provided, the thermal shutdown circuit takes over preventing the IC from overheating. The AZ78LXX are available in the plastic TO-92 (bulk or ammo packing), SOT-223 and SOT-89 packages. TO-92(Bulk Packing) TO-92(Ammo Packing) Nov. 2012 Rev. 2. 2 SOT-223 SOT-89 Figure 1.
