AP131-35WL-7 is a type of voltage regulator categorized as linear regulators and is used in PMIC applications. It is a low dropout (LDO) three-terminal regulator which is designed to provide low noise, high output accuracy and low ground-current operation. It can output up to 35W of output power which is the highest level of output power offered by AP131 series. It is capable of delivering outputs ranging from 1.8V to 18.0V.

Features:

• Low dropout voltage.
• Adjustable & fixed output voltage.
• Low output noise.
• High power delivery.
• High load regulation.
• Low ground current operation.
• Wide output voltage adjustment range.

Application Field:

AP131-35WL-7 can be used in a wide range of applications such as automotive systems, industrial systems, consumer systems, and computer systems. It is used to regulate the power supply of microcontrollers, as well as other circuits in order to prevent any problems caused by fluctuating input voltage. It is also used in cell phone base transceivers, PDAs, and other portable electronic devices.

Working Principle:

The working principle of the AP131-35WL-7 voltage regulator is based on the principle of negative feedback. It consists of an internal error amplifier and an output switch in order to achieve the desired output voltage. The voltage across the reference voltage is compared with the voltage across the feedback voltage. If the voltage across the reference voltage is higher than the voltage across the feedback voltage, the output switch is switched on which draws current from the input and supplies the output through the feedback path. The output voltage is maintained in this way to a certain accuracy and the output current may be drawn until the output voltage falls to a certain level below the input voltage. In case the output current is drawn beyond this level, the output will be disabled as a safety measure.

The AP131-35WL-7 voltage regulator also has a protection feature that prevents the circuit from current and thermal overloads. It has a current limit circuitry which senses the load current and shuts down when the current limit is reached. It also has an internal temperature sensing mechanism that uses a thermistor to detect any temperature surges and shuts down if the temperature is too high.

Overall, the AP131-35WL-7 voltage regulator is designed with high accuracy, low noise, and high power delivery to meet the varying requirements of different PMIC applications. The features, application field, and working principles provide the customers with an easy to use and reliable voltage regulator to fulfill the power and performance needs.
