Working Principles

The MAX1836EUT50+T is a low dropout linear regulator that regulates the output voltage to a constant level, regardless of changes in the input voltage or load conditions. It achieves this by using a pass transistor and feedback circuitry to maintain a stable output voltage.

When the input voltage is within the specified range, the regulator operates in a linear mode, where the pass transistor adjusts its resistance to maintain the desired output voltage. The feedback circuit continuously monitors the output voltage and adjusts the pass transistor accordingly.

In case of excessive heat buildup, the thermal shutdown protection feature activates, temporarily disabling the regulator to prevent damage. Once the temperature returns to a safe level, the regulator resumes normal operation.
