Wing Shing International Group 

7805A

3- Terminal Positive Voltage Regulators

Description

The 7805A 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.

Features

• Output Current In Excess of 1A

• Output Voltage of 5V

• Internal Short-Circuit Current Limiting & Thermal Overload Protection

• Guaranteed In Extended Temperature Range

Absolute Maximum Ratings (TA=25°C)
