Working Principles

The STM6315RAW13F is a low dropout voltage regulator that maintains a stable output voltage even when the input voltage drops close to the desired output voltage. It achieves this by utilizing a pass transistor that adjusts its resistance to compensate for the voltage difference between the input and output.

When the input voltage is higher than the desired output voltage, the pass transistor reduces its resistance, allowing current to flow from the input to the output. Conversely, when the input voltage approaches the output voltage, the pass transistor increases its resistance, limiting the current flow and maintaining a constant output voltage.

The enable pin allows the user to control the regulator's operation. When the enable pin is high (logic level 1), the regulator is enabled and provides the regulated output voltage. When the enable pin is low (logic level 0), the regulator is disabled, and the output voltage is not available.
