It offers low noise, high precision and wide input voltage range, with a maximum output voltage of 3.3 V. The device utilises a unique integrated circuit that enables it to operate with low dropout voltage, resulting in improved efficiency and noise reduction. The device is made up of a three-stage on-chip regulation technology along with built-in over-current protection and short-circuit protection.

Application Fields:

AP2114S-3.3TRG1 is widely used for a variety of applications, such as in cell phone, portable audio players, computers, digital cameras, and navigation systems. This device is also used for safe protection of circuits from over-voltage, over-current, and excessive temperature conditions, allowing for reliable and smooth operation. The device is available in SOT-23-5, SOT-23-6 and SOT-89 packages.

Working Principle:

The AP2114S-3.3TRG1 operates in a three-stage design that consists of a pre-bias, output, and load stages. In the pre-bias stage, the internal linear voltage regulator is used to regulate the input voltage down to a stable level that is suitable for powering the output device. At the output stage, the internal P-channel MOSFET acts as a switch mode regulator, providing a regulated output with low output voltage ripple. Finally, at the load stage, the ultra-low output dropout design enables efficient operation without the need for an external Schottky diode.

The AP2114S-3.3TRG1 also features an internal thermal protection circuit that will shut down the device in the event of excessive temperature. This thermal protection can prevent damage to the critical components due to excessive heat, making for reliable and safe operation.

In summary, the AP2114S-3.3TRG1 is a low dropout linear voltage regulator that provides a low output voltage ripple, wide input voltage range, and high precision and noise reduction performance. It is ideal for portable audio players, computers, digital cameras, and navigation systems, providing safe protection from over-voltage and over-current conditions.
