PMIC stands for Power Management Integrated Circuit, which is an integrated circuit (IC) that integrates multiple power management andor power regulation functions into a single package, such as Linear Voltage Regulators (LVRs). The AP2125KC-1.8TRG1 is a low-noise, highly accurate LVR which is designed to regulate output voltage during low line or high load conditions in voltage applications up to 1.8A.

Application Field

The AP2125KC-1.8TRG1 is a Linear Voltage Regulator designed for the general purpose switching power supply and DC/DC converter. It can power a variety of voltage regulators including switching power supplies, DC/DC converters, and voltage monitors. This IC is mainly used in automotive, communications systems, consumer electronics, PC peripherals, and industrial applications.

Working Principle

The AP2125KC-1.8TRG1 is an LVR that works by using a “feeback and control loop” system. The IC is connected to the power supply, and a feedback signal is fed into the IC. This feedback signal determines how much voltage is output to the load. The LVR then uses a comparator to regulate the output voltage by switching the internal circuitry depending on the feedback signal. This process enables the AP2125KC-1.8TRG1 to offer excellent voltage stability and precise voltage control, ensuring that the load always receives the required voltage. In the event of a surge or over-voltage, the protection circuit will detect this and shut down the output voltage automatically.

The AP2125KC-1.8TRG1 features excellent transient response, fast settling time and excellent line regulation. In addition, the device also features over-voltage/over-current/over-temperature protection and a power-on reset circuit, which helps it deliver reliable performance.

Conclusion

The AP2125KC-1.8TRG1 is an Liner Voltage Regulator designed to deliver accurate, reliable and safe power supply. It is an ideal solution for the general purpose switching power supply and DC/DC converting applications. The AP2125KC-1.8TRG1 offers excellent voltage stability and precise voltage control, as well as protection circuits and a power-on reset circuit, which helps it deliver reliable performance.
