LD1117DT18C is a Linear voltage regulator, which provides adjustable output voltage of 1.2V to 18V, allowing to adjust the current in wide range of 0.6A to 1.5A, using PNP-type power transistor. It is widely used in power supply and other applications.

The LD1117DT18C Working principle can be summarized with the following:

Under the Voltage Regulation circuit, LD1117DT18C is using PNP-type power transistor and two resistors to control the output voltage from 1.2V to 18V. It works mainly in two stages:

In the First Stage, the resistance value of the two resistors, typically R1 and R2 for Voltage Regulation, establishes the output voltage. This voltage, is the voltage between the voltage regulator and output pin, is usually referred to as ‘Vref’.

In the Second Stage, current flows through this voltage regulate circuit. This current is compared with a set reference voltage when the voltage regulator senses there is a difference between the reference voltage and the outside voltage. If the reference voltage is higher than the outside voltage, the transistor turns on, allowing more current to flow. As a result, the outside voltage increases. On the other hand, if the reference voltage is lower, the transistor turns off and the output current decreases, making the outside voltage decrease.
