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 Ordering Information Type NO.
