The working principle of the REG1117F33KTTTG3 is similar to other linear regulators, the output voltage is regulated by comparing an internal reference voltage to an input voltage. The voltage comparator will then control the output transistor to drive the output voltage to the desired level. The output voltage is subject to two factors – the output difference between the input and desired output voltage, and the output impedance of the device given in ohms. This output impedance is mainly due to the internal series pass transistor and its associated components.The output voltage is regulated by the control loop that is formed by the voltage comparator, feedback resistors, feedback capacitor, and the output transistor. The feedback resistors set the reference voltage, which is compared to the input voltage. The output transistor is then switched on and off in order to regulate the output voltage to the reference level. The output voltage can be adjusted by varying the resistance of the feedback resistors.The REG1117F33KTTTG3 is an adjustable voltage regulator with a wide input voltage range of 1.8V to 33V and an adjustable output from 1.25V to 33V. It is ideal for applications that require a low noise, low input voltage, and high efficiency step-down DC-DC power solution.
