Working Principle

The SP1086V1-L-3-3/TR is based on an error amplifier and a PNP input transistor. It is powered from a DC supply, usually between the 2.8V to 5.5V. The input voltage is regulated at the regulator output voltage by an error amplifier, which provides an output voltage of 3.3V. The output voltage is then controlled by changing the collector-base voltage of an NPN transistor located between the input and output terminals. When the voltage applied to the base of this transistor is changed by the error amplifier, the current drawn on the base of the regulator transistor is regulated in order to keep the output voltage constant.
