MC79L12ACP Description

Short technical summary and product information.

The ON Semiconductor MC79L12ACP is a 100 mA negative voltage regulator designed for various applications requiring a regulated negative voltage. This device features internal short circuit current limiting and thermal overload protection, making it a robust solution. It operates with a fixed output voltage of -12V and can supply up to 100mA of current.

 

The regulator is suitable for on-card regulation or other applications where a modest current level is needed. It offers advantages over traditional resistor-Zener diode circuits. The MC79L12ACP is available in a TO-92 package, designed for through-hole mounting.

 

Key electrical characteristics include a typical voltage dropout of 1.7V at 40mA and a PSRR of 42dB at 120Hz. The operating temperature range is from 0°C to 125°C. The device also includes protection features against over-temperature and short circuits.
