Description
3-terminal Positive Voltage Regulator
Manufacturer
Cystech Electonics Corp.
Datasheet
3-TERMINAL POSITIVE VOLTAGE REGULATOR
Description
The LM7805XE3 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
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.
LM7805XE3 is characterized for operation from 0 C to +125 C, and if operating temperature is
always high, please refer to the power dissipation curve.
Absolute Maximum Ratings
Typical Application
Note:
C1 and C2 are required if regulator is
located far from power supply filter
and load, or oscillation may induced
on the loop.
