Working Principles

The SC4215HSETRC is a linear voltage regulator that regulates the input voltage to a desired output voltage level. It achieves this by using a pass transistor and feedback mechanism. The feedback pin (FB) monitors the output voltage and adjusts the pass transistor accordingly to maintain a stable output.

When the input voltage exceeds the desired output voltage, the pass transistor reduces its conductivity, reducing the output voltage. Conversely, when the input voltage drops below the desired output voltage, the pass transistor increases its conductivity, raising the output voltage.
