7812 Linear Voltage Regulator, 12V 100mA, TO-92-3

The 7812 Linear Voltage Regulator from Texas Instruments is a fixed-output, 3-terminal positive regulator designed to deliver precise and stable power in a wide range of electronic applications. This versatile component is an ideal replacement for Zener diode/resistor combinations, offering significantly improved output impedance and lower quiescent current, making it an efficient solution for power management and industrial control systems.

With an output voltage of 12V and a maximum output current of 100mA, this regulator is well-suited for local on-card regulation, effectively eliminating distribution issues commonly associated with single-point power supplies. The device features built-in current limiting to keep the peak output current safe, along with safe area protection for output transistors to limit internal power dissipation. Should the internal temperature exceed safe levels, the thermal shutdown circuit automatically activates, preventing damage and ensuring long-term reliability.

The regulator accepts a wide input voltage range from 13.7V to 35V, providing flexibility in various system designs. It comes in a compact TO-92-3 package with through-hole mounting for easy integration onto printed circuit boards. Operating across a wide temperature range from -40°C to 125°C, this component delivers consistent performance even in demanding environments.

This voltage regulator also adheres to environmental standards, being a green product with no antimony (Sb) or bromine (Br). It offers output voltage tolerances of ±5% over the full temperature range, ensuring dependable output accuracy. Whether used in power management systems, industrial equipment, or custom electronics projects, this regulator provides a reliable and efficient power solution.
