Working Principles

The EL7586AILZ-T13 is a linear voltage regulator that maintains a stable output voltage regardless of variations in the input voltage or load conditions. It achieves this by using a pass transistor that adjusts its resistance to regulate the output voltage.

When the input voltage is applied, the regulator compares the feedback voltage at the FB pin with a reference voltage. If the output voltage is lower than the desired value, the pass transistor increases its resistance, allowing more current to flow and raising the output voltage. Conversely, if the output voltage is higher, the pass transistor decreases its resistance, reducing the current flow and lowering the output voltage.

The regulator also incorporates protection features such as thermal shutdown and short-circuit current limit to ensure safe operation under abnormal conditions.
