    L79L09ACUTR is a three-terminal, low-dropout (LDO) voltage regulator with a 9V fixed output voltage and a maximum output current of 800mA, which is suitable as a general-purpose power supply in many applications. The device is available in a SOT89-1 package and feature an optional logic compatible on/off output. The voltage regulator is designed to meet the requirements of both commercial and industrial grade applications.

    L79L09ACUTR application field include personal computation accessories, instrument, VCD/DVD player, set top box (STB), etc. It is also used in portable instruments, blue tooth devices, CCTV, digital/analog line card, notebooks, PDAs, irons, base station, routers, optical line terminal (OLT), camcorders, etc. These devices are suitable for voltage selection that does not exceed the maximum rating.

    The working principle of L79L09ACUTR is based on a linear regulator, where the output is regulated by modulating the input voltage with a variable resistance. When the output voltage is higher than the desired level, the resistance is slowly increased and the current flowing through the resistor is decreased. This leads to an overall decrease in the output voltage until it reaches the required level. The linear regulator offers good regulation, efficiency, and very high stability.

    The main features of L79L09ACUTR include a wide input voltage range, low quiescent current, excellent line and load regulation, great stability, and over-temperature protection. The device is capable of delivering up to 800mA of output current and is available in a variety of packages. The device also features an adjustable output voltage and adjustable current limit, making it suitable for a wide range of applications.

    In summary, L79L09ACUTR is a low-dropout (LDO) voltage regulator with a 9V fixed output voltage and a maximum output current of 800mA. It is suitable for a wide range of applications including personal computer accessories, instrument, VCD/DVD player, set top box (STB), portable instruments, blue tooth devices, CCTV, digital/analog line card, notebooks, PDAs, irons, base station, routers, optical line terminal (OLT), and camcorders.
