The AP7343D-14W5-7 is a type of voltage regulator belonging to the linear regulators family, mainly used for PMIC (Power Management IC) applications. This part consists of a step-down regulator, protection circuits, and a reference voltage, providing two regulated outputs of 1.8V and 5V respectively. The 7.5V to 24V input voltage range make this regulator an ideal choice for high power supply applications such as the voltage supplied by a battery or a power transformer.

The AP7343D-14W5-7 has a wide range of features that make it suitable for a variety of applications, such as a wide input voltage tolerance, regulated output voltage accuracy, protection against overvoltage, overcurrent and thermal shutdown, high efficiency, and low output noise. Its high efficiency rating of up to 95% and low quiescent current make it a reliable and energy efficient part.

The AP7343D-14W5-7 has a maximum output current of 140mA, ideal for low power applications such as USB on-the-go, wireless charging systems, interfacing circuits, and embedded systems. The output voltage accuracy of the regulator is excellent, with a max error of ±2% at the maximum rated current. It also has excellent protection against overvoltage and overcurrent faults.

When it comes to the working principle of the AP7343D-14W5-7, it is based on the Voltage Regulation Loop (VRL) concept. A separate circuit track is dedicated to each of the two voltage regulators. It includes an error amplifier, a reference voltage source, and a power MOSFET switch. The reference voltage source generates a reference signal. The error amplifier compares this reference signal with the actual output voltage and controls the turn on or turn off of theMOSFET switch to regulate the output voltage.

The use of the AP7343D-14W5-7 is recommended for PMIC applications in consumer electronic products, industrial control, and automotive systems due to its excellent performance. Its protection circuits and wide range of features make it reliable and easy to design with. Thus, it is suitable for both low and high power applications.
