document number 74823 www.vishay.com 10-dec-02 1 preliminary three-terminal low current positive voltage regulators description the MC78L00 series of positive voltage regulators are designed to provide a range of regulated power supply voltages for low current applications of up to 100ma. they are low cost, rugged, easy to use, three terminal devices with internal current limiting and thermal shut- down protection and are the low current members of the popular mc78m00 and mc7800 family.. no external components are required with the MC78L00 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. mechanical data case: so-8, sot-89, to-92 high temperature soldering guaranteed: 260?/10 seconds at terminals case outlines are on the back pages features ?wide selection of available fixed output voltages ?available in space saving sot-89 package ?low cost ?internal short circuit current limiting ?internal thermal overload protection ?no external components required complementary negative voltage regulators also available (mc79l00) ?accurate, 2% output voltage tolerance to-92 lp suffix s suffix sop-8 x suffix sot-89 1 2 3 1 2 3 4 8 7 6 5 1 2 3 output input cin 0.33 f MC78L00 co 0.1 f MC78L00 vishay formerly general semiconductor preliminary three-terminal low current positive voltage regulators standard application circuit gnd input 1 output 3 2 reference voltage starting circuit error amplifier current generator soa protection thermal protection series pass element internal block diagram MC78L00 vishay formerly general semiconductor
