3-TERMINAL POSITIVE VOLTAGE REGULATOR

Description

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.
