ON Semiconductor MC7815ACTG 15V 1A TO-220 Linear Voltage Regulator

The ON Semiconductor MC7815ACTG is a robust, monolithic positive voltage regulator integrated circuit designed to deliver a stable, fixed 15V output from a varying input voltage between 23V and 35V. Engineered for local, on-card regulation, it is a versatile solution for a wide variety of electronic applications, offering reliable performance with built-in protection for enhanced circuit safety.

This regulator incorporates several key internal protection features, including thermal overload protection, internal short-circuit current limiting, and output transistor safe-area compensation. These safeguards help prevent damage from overheating, excessive current, and operational stress, ensuring long-term reliability. With adequate heat sinking, the device can deliver a continuous output current in excess of 1.0 A. While designed as a fixed-voltage regulator, it can also be configured with external components to achieve adjustable voltages and currents, adding to its design flexibility.

Housed in a standard TO-220 through-hole package with three pins, the MC7815ACTG is suitable for a broad operating temperature range from 0°C to 125°C, making it resilient in various environmental conditions. Its design eliminates the need for external components for basic operation, simplifying circuit design and reducing bill-of-material costs.
