1.3.1 Supply Voltage
1.3.1 Supply Voltage
Most microcontrollers operate with the standard logic voltage of +5V. Some microcontrollers can operate at as low as +2.7V, and some will tolerate +6V without any problem. The manufacturer’s data sheet will have information about the allowed limits of the power supply voltage. PIC18F452 microcontrollers can operate with a power supply of +2V to +5.5V.
Usually, a voltage regulator circuit is used to obtain the required power supply voltage when the device is operated from a mains adapter or batteries. For example, a 5V regulator is required if the microcontroller is operated from a 5V supply using a 9V battery.
