PMIC (Power Management Integrated Circuit) Voltage Regulators are used to provide reliable voltage supply to different components of an integrated circuit. One such PMIC is the LM2936MP-3.0/NOPB from Texas Instruments. This is a linear, low dropout voltage regulator designed for a wide range of applications, ranging from providing an adjustable output voltage for general purpose applications to providing an adjustable output voltage for microprocessor and memory applications.

The LM2936MP-3.0/NOPB is built using cutting-edge and advanced technology, allowing it to achieve high reliability and accuracy while having a high efficiency rate. It includes an integrated low-dropout voltage regulator, alongside several other features such as under voltage, over voltage and over temperature protection. Additionally, the integrated dynamic power-down mode (DPM) enables the device to provide lower quiescent current, reducing power consumption and extending battery life in portable applications.

The LM2936MP-3.0/NOPB can provide an adjustable output voltage between 2.1V and 5.5V with a load current of up to 2.2A. It has a wide input voltage range from 4.5V to 6.5V and an operating temperature range from -40°C to +85°C, further expanding its application potential. The device also has a low quiescent current of just 1.3mA and a low dropout voltage of just 300mV, allowing it to be used in space and power-limited applications.

The LM2936MP-3.0/NOPB is ideal for both low-power and portable applications as it has an adjustable output voltage to suit different circuitry. It can be used in battery and adapter-operated applications such as smart phones, tablets, and other mobile devices, and also in fixed-voltage power supplies and many other applications. Furthermore, the LM2936MP-3.0/NOPB is an RoHS compliant device and includes a bulk gate Schottky diode for improved transient protection.

The LM2936MP-3.0/NOPB works by limiting the current passing through the regulator as it reduces the voltage to the predetermined output voltage. The voltage is regulated by comparing the regulator output voltage with a reference voltage which is usually provided by a voltage divider. The voltage divider creates a reference voltage that is proportional to the input voltage. The error amplifier compares the reference voltage with the regulator output voltage and sends the signals to the gate of the pass transistor. If the regulated output voltage is too high, the gate of the pass transistor is driven to be more conductive , thereby increasing the amount of current that passes through the regulator and reducing the output voltage. Similarly, if the output voltage is too low, the gate is driven to be less conductive , reducing the amount of current passing through the regulator and increasing the output voltage.

In conclusion, the LM2936MP-3.0/NOPB is a linear, low dropout voltage regulator that is ideal for low-power and portable applications. It has a wide input voltage range and an adjustable output voltage to suit different circuitry. Additionally, its low quiescent current and low dropout voltage makes it suitable to be used in space and power-limited applications.
