Working Principle

MC79L05ACP uses a negative voltage regulation to provide a constant output voltage. It uses the principle of the Zener diode, a device designed to have a reverse breakdown at a predetermined voltage. The Zener junction is connected in parallel with a constant current source that is adjusted so that the output voltage is set to 5V.The current drawn by the load connected to the output is monitored. If the current exceeds the rated overload current, then a protection device will be activated to cut off the current flow. This protection prevents the device from being overloaded or damaged.

Features

• Output voltage preset to 5V
• High input voltage up to 18V
• Low voltage dropout at 150mV
• Excellent overload protection of 150mA
• High output current up to 1A
• Robust and stable devices
• Low power consumption
• Small form factor
• Short circuit protection

Conclusion

MC79L05ACP is a great device for various electronic projects, such as AC-DC adapters or battery chargers. It is a robust and stable device and offers excellent overload protection and low power consumption. With its preset output voltage of 5V and high input voltage up to 18V, this device is a great choice for applications in different fields.
