AP1084TL-U is a voltage regulator in PMIC - Voltage Regulators - Linear category. It is designed to provide a reliable, accurate, and cost-effective solution for applications that require high voltage, low loss, and high current-carrying capacity.

AP1084TL-U has a fixed output voltage of 4.0V and an input voltage from 4.5V to 16V. The maximum output current it can provide is 5A and it features an extended frequency range of 50kHz to 400kHz. It is a high frequency switching regulator with low temperature drift and linear modulation.

The AP1084TL-U’s working principle is based on the buck converter topology. It uses a switching transistor to regulate the input voltage and provide a stable output voltage. The duty cycle of the switching transistor is adjusted according to the output signal of the control IC. The switching transistor is controlled by the current signal inside the control IC.

Compared to linear regulators, switching regulators offer better efficiency and faster response times. With a very fast switching speed and low temperature drift, the AP1084TL-U is ideal for applications that require high accuracy and tight voltage regulation such as audio amplifiers, DSLR cameras and other digital devices.

AP1084TL-U also features integrated protection and over-current protection, which prevents the device from damage due to over-currents. It has a two-wire, serial interface which can be used to program the output voltage of the device and to monitor the output current.

AP1084TL-U is an ideal solution for applications that require high efficiency, fast response time and excellent regulation in the 4 Volt range. With its simple architecture and integrated protection, it provides a cost effective solution for high voltage applications.
