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)
