PMIC - Voltage Regulators - Linear Application Field and Working PrinciplePMIC (Power Management IC) voltage regulator is a Linear regulator aligned to manage the power supply for equipment and components that require low noise, high efficiency, and accurate regulation. The AP2132MP-1.8TRG1 is one such regulator developed by AO3418.A Linear regulator is a simple low-dropout (LDO) power led composed of a transistor or FET and an output transistor in a package to adjust voltage and current levels.AP2132MP-1.8TRG1 is a Low Voltage Low Dropout Linear Regulator that is designed for ultra low quiescent current supply, requiring only 20mA (typical). This makes it highly efficient and cost-effective for small sensor and IoT applications such as battery-powered and portable devices. The device has a very low drop-out voltage making it suitable for applications where the supply voltage is close to the output voltage.The AP2132MP-1.8TRG1 is an LDO regulator with an adjustable output voltage of 1.8V and features over- temperature and short-circuit protection. The device is TSMC and AEC-Q100 qualified, making it suitable for automotive applications as well.The AP2132MP-1.8TRG1 is best suited for use in applications, such as battery-powered equipment, cellular phone, digital cameras, smart card, audio amplifier, automotive and industrial control products to achieve low drop out and low power dissipation.The AP2132MP-1.8TRG1 works on the basic concept of voltage regulation. Voltage Regulation is the process of controlling the output voltage of a power supply to match the requirement of the connected load. A voltage regulator has an adjustable voltage reference and a comparator circuit, that controls the transistor in the linear regulator to adjust the output voltage in order to match a preset level.The AP2132MP-1.8TRG1 follows this sequence as a voltage regulator. It regulates the voltage output to match the requirement of the connected load. It receives the input power from a supply or DC source, and regulates it to the required level by two stages of regulation, the output voltage stage, and the error amplifier. The output voltage stage is controlled by the error amplifier stage which is a negative feedback system composed of an internal voltage reference and a dut-defined reference amplifier.The first stage consists of an internal voltage reference and error amplifier to control the output voltage. The output voltage of this stage could be set externally via a voltage divider connection or by the included resistors in the Linear Regulator. The second stage is a simple linear regulator composed of a PNP transistor and an NMOS pass transistor to control the output voltage.The AP2132MP-1.8TRG1 has additional features such as Load Dump protection, Reverse Battery protection, and over-temperature protection which provides safety for the circuit. The over-temperature protection feature enables the device to active a shutdown when the temperature of the device exceeds the shutdown threshold.The AP2132MP-1.8TRG1 is an excellent Linear Regulator for applications which need low dropout and low quiescent current. It caters to the need of applications such as battery-powered and portable devices, automotive, and industrial control products. It has added features such as over-temperature and short-circuit protection to make the device safer, and has TSMC and AEC-Q100 qualification that makes it competent for use in Automotive applications.
