CYStech Electronics Corp. Three Terminal Medium Current Positive Voltage Regulators TO-252AB Spec. No. : C520J3 Issued Date : 2007.10.23 Revised Date :2011.10.31 Page No. : 1/12 TO-252AA LM78MXXJ3 Description IG O I G O The LM78MXXJ3 series of three-terminal positive regulators are available in the TO-252 package and with5V, 6V, 8V, 9V, 12V, 15V, 18V and 24V fixed output voltages, making them useful in a wide range of applications. These regulators can provide local on-card regulation, eliminating the distribution problems associated with single point regulation. Each type employs internal current-limiting ,thermal shut-down and safe operating area protection, making them essentially indestructible. If adequate heat sinking is provided, they can deliver over 500mA output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents.
