Useful ???????? Voltage regulator bL1118 You must know it in screen maintenance How voltage regulator works led Voltage regulator Voltage regulator Types These parts share a common name, which is 78xx as a positive linear voltage regulator and 79xx as a negative linear voltage regulator. The output voltage is determined by the last two digits xx, for example: 7803 outputs 03 volts Types These parts share a common name, which is 78xx as a positive linear voltage regulator and 79xx as a negative linear voltage regulator. The output voltage is determined by the last two digits xx, for example: 7803 outputs 03 volts 7805 outputs 05 volts 7806 outputs 06 volts 7809 outputs 09 volts 7812 outputs 12 volts Its advantages are simplicity of design and ease of use. It protects the circuit from drawing high power due to the nature of the load or due to a short circuit. It is considered an essential part in other circuits to regulate current, such as key voltage regulator circuits. Its disadvantages are that the input voltage must exceed the output voltage by at least two volts, otherwise the output voltage will decrease. The input voltage must not exceed a specific value, so that the voltage regulator does not overheat. It cannot supply the circuit with a large amount of current exceeding two amperes.
