PL7805J3 CYStek Product Specification
3-TERMINAL POSITIVE VOLTAGE REGULATOR
PL7805XJ3
Description
The PL7805XJ3 series of three-terminal positive regulators are
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.
PL7805XJ3 is characterized for operation from 0°C to +125°C, and if operating temperature is
always high, please refer to the power dissipation curve.
