3-TERMINAL POSITIVE VOLTAGE REGULATOR
Description
TO-220
The H7818_E series of three-terminal positive regulators are availa-
ble 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 shut-down 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.
H7818_E is characterized for operation from 0°C to +125°C, and if operating temperature is
always high, please refer to the power dissipation curve.
