| CYStech Electronics Corp. Three Terminal Low Current Positive Voltage Regulators Spec. No. : C515A3 Issued Date : 2003.03.26 Revised Date :2006.04.07 Page No. : 1/5 TO-92 LM78L05XA3 Description These regulators employ internal current-limiting and thermal-shutdown, making them essentially indestructible. They can deliver up to 100mA output current. if the case temperature can keep in Tc=25C. They are intended as fixed voltage regulators in a wide range of applications including local (on-card) regulation for elimination of noise and distribution problems associated with single-point regulation. In addition, they can be used with power pass elements to make high-current voltage regulators. The LM78L05 used as a Zener diode/resistor combination replacement, offers an effective output impedance improvement of typically two orders of magnitude, along with lower quiescent current and lower noise.
