Working Principle

The TCR2LE33,LM-CT series voltage regulator works on the low-dropout principle. The internal circuit of the voltage regulator is designed to maintain the output voltage constant regardless of variations in the input voltage or load current. It uses transistors and integrated rectifiers to achieve this.

In the step-up mode, the output voltage is set to the desired level using resistors connected between the output and feedback pins. When the output voltage is set to a level higher than the input voltage, the internal circuitry of the voltage regulator boosts the input voltage to produce the desired level of output.

In the step-down mode, the output voltage is set to a lower level than the input voltage. The internal circuitry of the voltage regulator regulates the input voltage to produce the desired level of output. It also reduces the quiescent current to ensure low power consumption.
