HSMC Product Specification

H78XX Series

3-TERMINAL POSITIVE VOLTAGE REGULATORS

Description

The H78XX series 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.

Features

• Output Current In Excess of 1A

• Output Voltages of 5V, 6V, 8V, 9V, 12V

• Internal Short-Circuit Current Limiting & Thermal Overload Protection

• Guaranteed In Extended Temperature Range
