The MC78M05BT is a fixed 5V voltage regulator. It belongs to the MC7800 family of linear regulators, and it is designed for a wide range of applications including industrial, telecommunications and computer peripherals.

MC78M05BT receives an input voltage of 8V to 20V and converts it to 5V with a maximum load current of 500mA. The device includes an integrated output switch, thermal protection, short circuit protection and current limit. This makes the regulator highly reliable and suitable for many applications.

The MC78M05BT boasts a full range of protections and monitor functions, including the switching regulator for quick transients, a low drop-out (LDO) regulator for higher current output and a diagnostic feedback loop for diagnostics.

The switching regulator provides regulation from as low as 6V and up to 20V. This allows the regulator to be used in applications where the input voltage may be highly variable. The low drop-out (LDO) regulator provides a steady 5V output even under conditions of high input ripple or noise.

The MC78M05BT is designed to operate over a wide input voltage range of 6V to 20V and features enable/disable, illuminator output, over-temperature protection and low EMI/RFI noise. The enable/disable pin allows the regulator to be turned on/off and the illuminator provides a fixed 5V output at up to 500mA with an enable pin.

The over-temperature protection monitors the die temperature during operation, and if the temperature exceeds a certain limit, the regulator shuts off to protect the device. The low noise and EMI/RFI levels of the device make it suitable for applications where EMI/RFI noise levels must be maintained. The package includes short circuit and over-current protection to ensure the safe operation of the regulator.

The MC78M05BT is a versatile and reliable voltage regulator for applications where input voltages may vary. It features a full range of protections and monitor functions to ensure reliable and safe operation, including the switching regulator for quick transients, a low drop-out (LDO) regulator for higher current output, over-temperature protection, low EMI/RFI noise and short circuit protection. The device is ideal for applications in industrial, telecommunications and computer peripherals, and is UL and CE approved.
