CYStech Electronics Corp. Spec. No. : C511J3 Issued Date : 2003.03.25 Revised Date :2005.09.15 Page No. : 1/3 Three Terminal Positive Voltage Regulators LM78D05XJ3 These voltage regulators are monolithic integrated circuits designed as fixed voltage regulators for a wide variety of applications including local, on-card regulation. These regulators employ internal current limiting, thermal shutdown, and safe-area compensation. With adequate heatsinking they can deliver output currents in excess of 1.0A. Although designed primarily as fixed voltage regulator, these devices can be used with external components to obtain adjustable voltages and currents.
