The L7905CV is a 3-terminal negative voltage regulator with a voltage range of -5V to -22V and a maximum current output of 1.5A. This device is part of the PMIC voltage regulator family of products and is a drop-in replacement for other linear voltage regulator parts. This device is mainly used in industrial equipment, consumer electronics, power supplies, and various other applications where a reliable low current power source is required.

The L7905CV provides a flat and corss-load regulation to ensure consistent output voltage performance. The voltage is adjustable by means of an external resistor, so the device can easily and quickly be tailored to meet different needs in various applications. The device also includes over-temperature and current limiting protection, to guarantee that it can operate safely in any environment.

The working principle of the L7905CV is based on a negative charge pump with an attached load switch, which is used to regulate the output voltage. The internal circuitry limits the current in the load switch, which keeps the output voltage at a consistent level. This process is commonly referred to as "linear" voltage regulation, because it is a relatively simple and consistent method for maintaining a stable voltage output.

The L7905CV is an excellent choice for applications that require a reliable and highly accurate negative voltage regulator. Its simple configuration, adjustable output, and wide operating range make it the perfect choice for powering a variety of devices. This device is also highly efficient and easy to use, making it a great choice for any application where a reliable, low current power source is needed.
