The AP139-30WL-7 is a linear voltage regulator in the PMIC (power management IC) family.

Linear voltage regulators are used primarily to drop a voltage from a higher voltage source, such as a battery. There are two types of linear voltage regulators -- the standard linear regulator, and the switching regulator. The linear regulator works with a constant voltage input and current output, while the switching regulator switches between a high voltage and low voltage state in order to deliver the desired output. The AP139-30WL-7 is a linear regulator.

The AP139-30WL-7 is designed with a wide input voltage range and can operate over a temperature range of -40°C to +125°C. It is capable of supplying a current of 30W and a maximum output voltage of 7V. The AP139-30WL-7 offers an ultralow quiescent current of 40mA, making it suitable for applications that require a low power consumption. The AP139-30WL-7 is intended to be used in a variety of applications, including LED display backlighting, mobile device power management, and satellite power supplies.

The AP139-30WL-7 works by using an internal MOSFET to regulate the voltage across the load. The voltage is sensed at the output terminal of the regulator and compared to an external reference voltage. This reference voltage is typically set to the desired output voltage. If the voltage at the output terminal is higher than the reference voltage, the internal MOSFET will increase the current to reduce the output voltage. Conversely, if the voltage at the output terminal is lower than the reference voltage, the current is decreased to raise the output voltage. This process is done on a continuous basis, so that the desired voltage is maintained at the output terminal of the regulator.

In addition to the standard features, the AP139-30WL-7 also offers several other features that make it suitable for a number of applications. These features include thermal shutdown and current limit protection, enable operation from a single supply, and a low dropout voltage. It also offers low noise, high PSRR, high accuracy and low output voltage deviation.

The AP139-30WL-7 is an excellent choice for a wide range of applications that require a low power, high efficiency, and reliable power supply. The wide input voltage range and high output voltage accuracy make it an ideal choice for powering mobile devices and LED displays, especially where low power consumption is a must.
