STMicroelectronics L79L12ACZ Voltage Regulator

The L79L12ACZ from STMicroelectronics is a reliable and efficient fixed-output voltage regulator designed specifically for applications requiring a regulated -12V power supply. This component is part of the L79 series, which is known for providing negative voltage regulators with a wide range of available fixed output voltages, making them suitable for a variety of electronic applications.

The L79L12ACZ is capable of delivering up to 100mA of output current, which is ideal for low power consumption devices. Its output voltage is preset to -12V, with a precision of output voltage maintained within a 4% tolerance under specified input voltage and output load conditions. This level of accuracy is essential for sensitive electronic circuits that rely on a stable power supply for optimal performance.

This voltage regulator features thermal overload protection, which safeguards the device and the electronic system it powers from damage due to excessive heat. Additionally, the L79L12ACZ includes short circuit protection, ensuring that the regulator and the connected components remain safe in the event of a fault condition. These protection features contribute to the reliability and longevity of both the regulator and the overall system.

The L79L12ACZ comes in a TO-92 package, which is a widely used through-hole mounting package. This package type allows for easy integration into various circuit designs and is particularly favored for prototyping and small production runs. The compact size of the TO-92 package makes it suitable for space-constrained applications, while still offering adequate power dissipation capabilities.

STMicroelectronics' commitment to quality is evident in the L79L12ACZ, which is designed and manufactured to meet the stringent standards for which ST is known. With its reliable performance, built-in protection features, and versatile package design, the L79L12ACZ is an excellent choice for designers and engineers looking for a negative voltage regulator for their electronic projects.
