Working Principles

The LM3710YQMM-232/NOPB operates as a linear voltage regulator. It takes an input voltage within the range of 2.7V to 5.5V and regulates it to a stable output voltage between 1.2V and 3.6V. The feedback pin (FB) is used to set the desired output voltage by connecting external resistors. The enable pin (EN) controls the on/off state of the regulator.

When enabled, the IC compares the feedback voltage with a reference voltage and adjusts the pass transistor accordingly to maintain the desired output voltage. If the output current exceeds the specified limit or the temperature rises above the threshold, the overcurrent and thermal shutdown protections come into play, ensuring the safety of the connected devices.
