3-TERMINAL POSITIVE VOLTAGE REGULATOR

Description

The H7808_I series of three-terminal positive regulators are

available in the TO-251 package and with several fixed output

voltages, making it useful in a wide range of applications. These regulators can provide local

on-card regulation, eliminating the distribution problems associated with single point regulation.

Each type employs internal current limiting, thermal shut-down and safe operating area

protection, making it essent-ially 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.

H7808_I is characterized for operation from 0

°C to +125°C, and if operating temperature will al-
