LM78M05XA3

CYStech Electronics Corp. Three Terminal Medium Current Positive Voltage Regulators Spec. No. : C520A3 Issued Date : 2003.03.27 Revised Date :2006.05.29 Page No. : 1/4 TO-92 LM78M05XA3 Description These regulators employ internal current-limiting and thermal-shutdown, making them essentially indestructible. They can deliver up to 500mA output current, if the case temperature can be kept at Tc=25°C. 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 LM78M05XA3 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.
