Working Principles

The PAM3101FKF285 is a linear voltage regulator that uses a pass transistor to regulate the output voltage. It operates by comparing the feedback voltage (FB) with a reference voltage to adjust the pass transistor's resistance and maintain a stable output voltage. When the input voltage (VIN) is higher than the desired output voltage (VOUT), the pass transistor conducts and regulates the output voltage accordingly. In case of excessive heat buildup, the thermal shutdown protection feature activates, disabling the pass transistor to prevent damage.
