LM2936MPX-5.0/NOPB

PMIC, which stands for Power Management Integrated Circuit, is closely associated with various advantages in the generation, conversion, and distribution of power in an electronic device. It’s role is to provide optimum power to the various components in a device so as to guarantee its reliability and energy efficiency. The voltage regulators are an important subcategory of PMIC that aims to regulate and stabilize the output of the power supply. Within the category of voltage regulators, LM2936MPX-5.0/NOPB stands out as one of the most popular and widely used devices. This is due to its high-efficiency power delivery, low power consumption, and large number of features and capabilities. In this article, we’ll take a closer look at the application field and working principle of LM2936MPX-5.0/NOPB.

Application Field

LM2936MPX-5.0/NOPB has wide applications in consumer electronics, industrial and automotive fields. The device is capable of delivering a maximum output current of 1.5A and is available in different packages, both in TO-220 and DPAK form. This makes the device ideal for a range of applications, from mobile phones and notebooks to industrial control systems. The device also supports a wide input voltage range, ranging from 3V to 20V, making it suitable for various kinds of voltage sources. The device provides a number of protection features, such as reverse voltage protection, over-temperature protection, current limiting, and output short-circuit protection.

Working Principle

The LM2936MPX-5.0/NOPB can be considered to be a two-stage linear voltage regulator. It consists of two stages: the first stage regulates the voltage to an adjustable voltage, while the second stage operates in buck-boost mode and delivers current to the load. The device has two independent outputs that can be adjusted to the required voltage levels. The output voltage can be adjusted using two resistors, connected in a voltage divider configuration. The output voltage can also be adjusted by varying the resistive load, since the output voltage is proportional to the load current.

To provide a stable output voltage, the device utilizes an internal error amplifier to compare the input and output voltages. When the output voltage is lower than the reference voltage, the current generated by the Voltage Regulator is increased, thus providing the necessary voltage to maintain the desired output voltage. On the other hand, if the output voltage exceeds the reference voltage, the current output is reduced accordingly.

Features and Specifications

The LM2936MPX-5.0/NOPB provides a number of features and specifications that makes it suitable for a range of applications. It has an adjustable output voltage range of 3V – 20V and a maximum output current of 1.5A.
