PL7818XJ3

CYStech Electronics Corp. 3-TERMINAL POSITIVE VOLTAGE REGULATOR Spec. No. : C527J3 Issued Date : 2003.04.02 Revised Date : Page No. : 1/3 PL7818XJ3 Description The PL7818XJ3 series of three-terminal positive regulators are TO-252 available in the TO-252 package. These regulators can provide local on-card regulation, eliminating the distribution problems associated with single point regulation. Each employs internal current limiting, thermal shutdown and safe operating area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents. PL7818XJ3 is characterized for operation from 0°C to +125°C, and if operating temperature is always high, please refer to the power dissipation curve.
