MC79L12ABDR2G Description

Short technical summary and product information.

The MC79L12ABDR2G is a negative voltage regulator from On Semiconductor, designed for applications requiring a regulated negative voltage up to 100 mA. This device features internal short circuit current limiting and internal thermal overload protection, making it a robust solution for various power management needs.

 

With a fixed output voltage of -12V, this regulator is suitable for on-card regulation or other applications where a modest current level is required. It operates within a temperature range of -40°C to 125°C and is available in an 8-SOIC package, suitable for surface mount applications.

 

The regulator offers a typical voltage dropout of 1.7V at 40mA and provides a PSRR of 42dB at 120Hz. Its design aims to offer advantages over traditional resistor/Zener diode configurations, simplifying circuit design and improving reliability.

 

Key features include its integrated protection mechanisms and ease of use, often requiring no external components for basic operation. The 8-SOIC package is standard for many surface-mount designs, facilitating integration into compact electronic systems.
