ON Semiconductor MC7800/DMC7800/MC7800A/NCV7805 1.0A Positive Voltage Regulators Datasheet
The document describes monolithic integrated circuits designed as fixed-voltage regulators for a wide variety of applications, including local and on-card regulation. These regulators feature internal current limiting, thermal shutdown, and safe-area compensation to ensure reliable operation.
Although primarily designed as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents. The series includes various models such as the MC7805B/C, MC7806B/C, and MC7806AC, offering output voltages in 2% and 4% tolerance.
