The L4931CV50 is a linear voltage regulator that is widely used in power management circuits. It provides a continuous output voltage at low dissipation levels and has good current regulation, low noise and tight voltage regulation. This integrated circuit can be used for many applications, including mobile phones and other portable electronic devices.
Application Field
The L4931CV50 is typically used as an adjustable output regulator, meaning its output voltage can be adjusted by means of adjustments to the feedback voltage. It is commonly used in battery-powered and long-term operations, such as portable devices and power control circuits. Also, they are used in automotive electronics, telecommunications, office machines, instrumentation and desktop PCs.
L4931CV50 is suitable for providing a steady voltage supply to a wide range of digital and analogue circuits. Also, it can be used for other purposes such as providing power to linear and switching regulators for eliminating voltage drops in the line and for current limiting protection. Motor control systems, audio and video systems can be supplied by L4931CV50s.
Working Principle
The L4931CV50 is a three terminal PIN device with an adjustable current and input voltage. This device is a linear voltage regulator, meaning it regulates the output voltage between two pins (positive and negative) by applying the control voltage to the third pin (control pin). This integrated circuit works on the principle of negative feedback control by varying the voltage of the control pin compared to the output voltage to maintain a constant voltage output.
The output of the device is regulated according to the input voltage and the feedback voltage. The linear regulator works primarily in two modes, the cut-off mode and the overload mode. In the cut-off mode, the output voltage is held constant and the device will shut down the output voltage when the input voltage exceeds a certain range. In the overload mode, the device senses the output voltage and will adjust the output voltage to keep it in the specified range.
