The LP3874EMP-ADJ/NOPB belongs to the family of non-isolated, constant-current/constant-voltage linear regulators, which are part of the Power Management ICs (PMICs) involved in voltage regulation. It has an adjustable output voltage range, making it suitable for a variety of applications.

The working principle of the LP3874EMP-ADJ/NOPB linear regulator is simple: it accepts a voltage input and produces a regulated output voltage, thanks to its feedback loop. The regulator continuously compares the output voltage to the reference voltage, adjusting its output to the desired value if it varies. The LP3874EMP-ADJ/NOPB also has a constant-current adjustment which helps regulate the current output of the regulator.

The LP3874EMP-ADJ/NOPB is suitable for a wide range of applications in need of a regulated output voltage, including portable and handheld medical devices, as well as consumer electronics products such as digital cameras and laptop computers. Furthermore, the regulator is compliant with the stringent Medical EMC Standard safety requirements and is particularly suited for telemedicine and other medical systems.

The LP3874EMP-ADJ/NOPB is ideal for applications where space is limited, as the regulator requires a very small footprint due to its integrated design. It integrates both voltage regulation and current regulation in a single package and is available in a 2mm x 3mm TDFN-10 package. Furthermore, its operating temperature range, from -40°C to +85°C, makes it suitable for a broad range of applications in the industrial, automotive and consumer market.

In addition, the LP3874EMP-ADJ/NOPB is designed to consume very low power and offers an improved current-mode control, providing better thermal performance and faster transient response. The regulator has an efficiency of up to 95%, depending on the system load. It also has a 300kHz switching frequency, which increases the power density by up to two times compared to conventional linear-regulator solutions.

The LP3874EMP-ADJ/NOPB linear regulator is a compact, low-power and high-performance solution for voltage regulation. It is particularly suited for consumer and portable medical applications, thanks to its small size, low quiescent current, high efficiency and adjustable output voltage range.
