The transistor 2N797 is a diode with multiple functions, while the 2N2222 is a silicon NPN transistor. The reference voltage in the circuit is created by the voltage difference between these two devices, typically around 0.5 volts. The LM111 is not a standard operational amplifier but is specifically designed for use as a high-performance voltage comparator with very low input current. When powered by a 5V supply, its output can be adjusted to reach as low as 0V. With the circuit shown, the minimum output voltage can be fine-tuned to be nearly zero. Additionally, the entire stabilization circuit has an extremely low temperature coefficient, ensuring stable performance across a wide range of operating conditions.
Steel pole is a long cylindrical structure made of steel that is commonly used for a variety of purposes, such as supporting structures, supporting wires or as a decorative element in landscaping. Steel rods are known for their durability, strength, and corrosion resistance, making them a popular choice for outdoor applications. They come in a variety of sizes and shapes depending on the specific requirements of the project.
