The AP1184T5-25L-U features an extreme low drop-out voltage of 1.8V and can operate over a wide input voltage range of 4.5V to 25V. It is also capable of outputting up to 1.8A of current, making it suitable for a variety of applications. It is an ideal solution for those looking for a low-cost and reliable voltage regulator.

Working Principle

The AP1184T5-25L-U is a linear voltage regulator which uses a three-terminal voltage regulator integrated circuit (VREG IC) to provide a low-noise, stable voltage output. The VREG IC is a monolithic integrated circuit containing an internal power MOSFET and an error amplifier to regulate the output voltage.The AP1184T5-25L-U IC contains two separate phases which run in parallel to reduce power dissipation and improve efficiency. One phase provides the majority of the output current while the second phase acts as a current doubler for low load conditions. This multi-phase architecture reduces total power dissipation and enhances overall efficiency.The VREG IC is also protected against over-voltage and current conditions by over-voltage and over-current protection circuitry. In the event of an overload condition, the VREG IC enters a safe mode of operation and shuts down to protect the device from damage.

Conclusion

The AP1184T5-25L-U is a multi-phase voltage regulator which is ideal for a wide range of consumer and industrial applications. Its high efficiency and low-noise operation make it suitable for powering low-power computing systems and Power over Ethernet modules. It provides an extreme low drop-out voltage of 1.8V over a wide input voltage range of 4.5V to 25V, and is capable of outputting up to 1.8A of current. The AP1184T5-25L-U IC also features over-voltage and over-current protection circuitry to protect the device from damage in the event of an overload condition.
