AUK S7805P

S7805P
Semiconductor
Fixed Voltage Regulator
Descriptions
The S7805 series are three-terminal positive regulators providing over 1A output current
with internal current limiting, thermal shutdown and safe area protection. These regulators
are useful in a wide range of applications. Although they are just fixed voltage regulators,
the S7805 series can be used with external components to obtain adjustable voltages and
currents.
Features
• Internal Short Circuit Current Limiting
• Maximum Output Current (1A Max.)
• Thermal Overload Protection
• Output Transistor Safe Area Protection
