Working Principles

The LM3535TME/NOPB is a linear voltage regulator that provides a stable output voltage regardless of changes in the input voltage or load conditions. It achieves this by using a feedback mechanism that adjusts the internal circuitry to maintain a constant output voltage.

When the enable pin (EN) is high, the regulator is enabled and starts regulating the output voltage. The input voltage (VIN) is supplied to the regulator, and the output voltage (VOUT) is regulated based on the feedback received from the FB pin. The GND pin is connected to the ground reference.

The LM3535TME/NOPB also incorporates thermal shutdown protection and short-circuit current limiting to ensure safe operation under various conditions.
