Working Principle

The LD6806TD/28H,125 linear regulator works on the same principle as a diode regulator, but with a more flexible and efficient design. The regulator uses a transistor in a negative feedback loop to adjust the output voltage based on the input voltage, thus keeping the output voltage constant within a certain range. This transistor is an N-channel MOSFET, which is controlled by a voltage reference and a feedback loop. When the input voltage changes, the output of the regulator is regulated by the reference voltage, which is also contained within the feedback loop.

When the input voltage is higher than the reference voltage, the feedback loop causes the transistor to decrease the current flow through the line, thus reducing the output voltage. Similarly, if the input voltage is lower than the reference voltage, the feedback loop causes the transistor to increase the current flow through the line, thus increasing the output voltage.

Conclusion

The LD6806TD/28H,125 linear regulator is a reliable and efficient regulator that is widely used in a variety of applications. Its low power dissipation and high peak output current make it an ideal choice for power supplies and other power related applications. Its low quiescent current and efficient design allow it to provide a stable and steady output voltage, making it a valuable addition to any electronic system.
