Working Principle

The S-1135B12-A6T1U voltage regulator operates on the principle of voltage regulation. It incorporates two stages: the pre-regulation stage and the voltage feedback stage. In the pre-regulation stage, the chip regulates the input voltage through two resistors and a transistor. The output of the stage is an adjustable DC train that is then fed to the voltage feedback stage. In the voltage feedback stage, an external reference voltage is applied to an internal voltage divider comprising regulated, resistive voltages. This regulated voltage is then compared with external feedback voltage. The difference between these two voltages is then used to control internal transistor switch to adjust output voltage as needed.

In order to maximize the performance, the S-1135B12-A6T1U utilizes adaptive on-time control, over current protection and voltage trimming to ensure that the output voltage is always maintained within the desired range. Additionally, it uses an adjustable power-on-delay and soft-start feature to reduce inrush current and extend its life span.
