3-TERMINAL POSITIVE VOLTAGE REGULATOR
PL7812XE3
Description
The PL7812XE3 series of three-terminal positive regulators are
available in the TO-220AB package. These regulators can provide
local on -card regulation, eliminating the distribution problems
TO-220AB
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.
PL7812XE3 is characterized for operation from 0°C to +125°C, and if operating temperature is
always high, please refer to the power dissipation curve.
