Working Principle

The LT1790AIS6-1.25#TRPBF’s working principle is based on the use of a differential amplifier. It consists of an internal reference source, which generates a stable reference voltage, and an external resistor-capacitor (RC) network connected between the amplifier’s input and output. The differential amplifier acts as a voltage follower, which amplifies the voltage difference between its input and output.

When the voltage at the input is lower than the reference voltage at the output, the differential amplifier amplifies the voltage difference. The amplified voltage is then compared with the internal reference voltage and the output is adjusted accordingly. This ensures that the output voltage does not deviate from the reference voltage by more than a certain margin.
