The P-channel pass transistor receives data from the error amplifier, over-current shutdown, and thermal protection circuits. During normal operation, the error amplifier compares the output voltage to a precision reference. Over-current and Thermal shutdown circuits become active when the junction temperature exceeds 175℃, or the current exceeds 350mA. During thermal shutdown, the output voltage remains low. Normal operation is restored when the junctio.
