Additional Details

The PQ1L333M2ZPH typically operates with an input voltage range of 3.6V to 10V. The dropout voltage is typically around 0.2V at the rated output current. The regulator's overcurrent protection limits the output current to a safe level, preventing damage in case of a short circuit or overload. The thermal shutdown protection prevents thermal runaway by shutting down the regulator when the junction temperature exceeds a specified threshold. The compact surface-mount package is suitable for automated assembly and minimizes board space requirements. The regulator is ideal for applications where stable, efficient, and protected power supply is required. It is designed for efficient heat dissipation.
