It regulates the power supply to the device and supports a maximum output current of 1A.Working Principle of L7915CVThe L7915CV is a fixed voltage regulator, with an output voltage of -15V. It works on the principle of linear regulation. The input voltage is applied to the input terminal, which then passes through an internal voltage regulator, which reduces the voltage to the desired output voltage. The voltage regulator then passes the reduced voltage to the output terminal. The output current is limited by an internal current limiter. The device also has protection against reverse input voltages, over current, and thermal overload. The L7915CV also has a low noise output, which eliminates the need for external filtering, as well as a low dropout voltage and low quiescent current. It also has an internal current limiter and over-current protection, making it very reliable in case of short circuits or overload.ConclusionThe L7915CV is a three-terminal, fixed voltage regulator, with an output voltage of -15V. It is mainly used in converters and printers, automotive, industrial, and consumer applications, including notebook and tablet computer power systems. It works on the principle of linear regulation and has a very low output noise, an output current capability of up to 1A, low dropout voltage, and low quiescent current.
