Integrated circuits form one of the most crucial components for modern electronic systems, with power management ICs (PMICs) being one of the most important. PMICs, usually classified by their functions, are integrated circuits for power management and include voltage regulators, battery charging controllers, and DC-DC converters among many others. Linear voltage regulators, the focus of this article, remain the most popular type of voltage regulator, especially in applications that require voltage regulation with low noise and good regulation accuracy.

The LP3852ET-2.5/NOPB is a linear regulator, produced by Texas Instruments and is part of the company’s low-power series of devices. This linear regulator operates with a wide input voltage range and is suitable for applications requiring precise output voltage regulation. The regulator is fully protected with thermal shutdown, providing protection against over-current conditions. This integrated circuit can deliver a precise regulated output voltage with a low dropout, making it a great choice for power management applications.

The LP3852ET-2.5/NOPB application field ranges from general-purpose power supplies and low-voltage applications to high-current or high-DCR floating point regulation applications. It has a wide input voltage range from 1.3V to 6V, making it ideal for use in battery powered systems. This device features a superior current limit and thermal shutdown protection, making it an excellent choice for power management in a large variety of applications. This device also features a fast start-up time of 5-­μs, making it reliable for quick power-on.

The LP3852ET-2.5/NOPB basic working principle includes its step-down function, which is also called a “switching” regulator because it uses transistors to step down the voltage. When input voltage is applied, the integrated circuit’s internal MOSFET or PNP transistors generate an on-off switching waveform. These switching waveforms generate a low-voltage current through an inductor, which is then filtered by the output capacitor. The output capacitor filters the current waveforms, resulting in a flat, regulated output.

The LP3852ET-2.5/NOPB linear voltage regulator is a great choice for combining a wide input voltage range with low dropout performance, making it ideal for applications such as powering microprocessors and other logic devices. Its internal protection features make it reliable and easy to design with in a variety of applications requiring precise voltage regulation, offering protection against thermal runaway and over-current conditions.
