3-TERMINAL POSITIVE VOLTAGE REGULATOR
Description
TO-252
The H7809_J 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 shut-down and safe operating area protection, making it
essen-tially 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.
H7809_J is characterized for operation from 0°C to +125°C, and if operating temperature is
always high, please refer to the power dissipation curve.
