The transistor 2N797 for the diode is a manifold, and the 2N2222 is a silicon tube. The reference voltage is generated by the gap voltage difference between the two tubes and has a value of approximately 0.5V. The LM111 is not a normal op amp, but is designed to design a voltage comparator with very low input current. When powered from a 5V supply, its minimum output voltage can be adjusted to 0V. With the circuit shown in the figure, the minimum output voltage can be adjusted to be close. The temperature coefficient of the entire stabilization circuit is also very low.
This scratch-resistant TPU Film protects your new AirTag from daily wear and tear. It can be easily glued to the back to keep the shiny silver in its original condition. In addition, the AirTag screen protector with "self-healing" function can automatically repair small scratches and bubbles within 24 hours. This means you can continuously enjoy the new look and appearance of AirTag without worrying about serious scratches and dents.
The Apple Airtag TPU Film can perfectly fit your AirTag skin. It is designed to provide the maximum coverage for your AirTag metal panels. Compatible with most AirTag shells. Leave extra space around the frame so that your shell can wrap the edges of the AirTag without interfering with the film.
The 0.14mm ultra-thin AirTag Screen Protector allows you to enjoy the maximum resolution while being thin enough to make the AirTag sensitive to the original signal response, ensuring that it will not affect any user experience. You won't even notice that the screen protector is there, so your Apple logo can still be displayed.
The AirTag Tracker Screen Protector is very easy to apply and is specially designed for your AirTag. Just clean your AirTag and install it on the surface to eliminate all bubbles and get the job done!
