MC79L00 Vishay New Product formerly General Semiconductor Three-Terminal Low Current Negative Voltage Regulators TO-92 1 LP Suffix 2 3 Features Description * Wide selection of available fixed output voltages The MC79L00 series of negative voltage regulators are designed to provide a range of regulated power supply voltages for low current applications of up to 100mA. * Low cost * Internal short circuit current limiting * Internal thermal overload protection * No external components required * Complementary positive voltage regulators also available (MC78L00) * Accurate, 2% output voltage tolerance They are low cost, rugged, easy to use, three terminal devices with internal current limiting and thermal shutdown protection and are the low current members of the popular MC79M00 and MC7900 family. No external components are required with the MC79L00 in most applications. These products offer an improved replacement for the traditional zener-resistor combination, providing better output impedance, lower internal power dissipation and lower quiescent current.
