MC79L12ACPRA Description

Short technical summary and product information.

The ON Semiconductor MC79L12ACPRA is a 100 mA negative voltage regulator designed for various applications requiring a regulated negative voltage. It operates with an input voltage up to -35V and provides a stable -12V output.

 

Key electrical specifications include a maximum output current of 100mA, a typical dropout voltage of 1.7V at 40mA, and a PSRR of 42dB at 120Hz. The device incorporates internal short circuit current limiting and thermal overload protection, making it robust for demanding applications. It requires no external components for basic operation.

 

This regulator is housed in a TO-92 (TO-226) package with through-hole mounting. The operating temperature range is from 0°C to 125°C. The MC79L12ACPRA is suitable for on-card regulation or other applications needing a regulated negative voltage at a modest current level.
