L387AH

L387AH is an integrated linear voltage regulator widely used in various fields and applications. This voltage regulator can provide reliable and efficient power conversion for various types of microcontrollers, as well as for a variety of power supplies, including DC converters, ACsupplies and linear supplies. This regulator integrates a blocking diode for reverse polarity protection, eliminating the need for external protection diodes. The L387AH linear voltage regulator also provides protection from overloads, short circuits and overvoltage.The L387AH linear voltage regulator is designed with a free-wheeling diode, allowing for an increase in power, as well as a lower dropout voltage. This provides the stability and reliability needed in applications where higher input voltages are used. Additionally, the L387AH features low power consumption and low noise.The working principle of the L387AH linear voltage regulator begins with the input voltage being converted to a lower voltage. This voltage is then regulated by the output stage of the regulator. A voltage drop across the regulator is generated due to the output current, and this produces the output voltage. The regulation of the output voltage is accomplished by adjusting the voltage drop across the regulator by changing its resistance. The output voltage of the L387AH linear voltage regulator is also adjustable, allowing it to be tailored to meet the needs of the application. The voltage adjustment is easily achieved with the addition of a voltage-divider network. The output voltage can then be adjusted by changing the ratio of the resistors in the voltage-divider network.The L387AH linear voltage regulator is an ideal solution for many applications requiring a low-power, low-noise voltage regulator. It is suitable for applications such as microcontroller power supplies, DC converters, AC supplies, and linear supplies. This regulator can provide a stable, reliable and efficient power conversion solution, ensuring that the device or circuit being powered operates correctly and efficiently.
