ONSEMI MC79L12ACPG Negative Voltage Regulator, -12V, TO92-3, 100mA

The ONSEMI MC79L12ACPG is a fixed, negative linear voltage regulator designed to deliver a stable -12V output at up to 100mA. It is ideal for applications requiring a regulated negative rail at modest current levels, such as motor drive control and on-card regulation.

This regulator incorporates internal short-circuit current limiting and thermal overload protection, making it remarkably rugged and reliable in demanding conditions. In most applications, no external components are required for operation, simplifying design and reducing component count.

The device comes in a compact TO92-3 package with through-hole mounting for easy integration. It is available in the 7912 voltage regulator series and operates over a temperature range of 0°C to 125°C, ensuring consistent performance across a wide range of environments.
