If adequate heatsink is provided,they can deliver up to 100 mA output current.They are intended as fixed voltage regulators in awide range of applications including local oron-card regulation for elimination of noise anddistribution problems associated with single-pointregulation. In addition, they can be used withpower pass elements to make high-currentvoltage regulators.The L78L00 series used as Zener diode/resistorcombination replacement, offers an effectiveTO-92output impedance improvement of typically twoorders of magnetude, along with lower quiescentcurrent and lower noise.BLOCK DIAGRAMNovember 20001/19
