LP2985AIM5-4.7/NOPB is a linear voltage regulator integrated circuit manufactured by Texas Instruments. It is categorized as part of their Power Management Integrated Circuit (PMIC) product line under the Voltage Regulators Linear family. It is a low-dropout (LDO) regulator and is designed to produce a fixed output voltage of 4.7V.

The LP2985AIM5-4.7/NOPB is designed with a low quiescent current of 20 μA and consumes up to 175mW. It also has a low dropout voltage of 800mV while operating at full load. It also offers a wide range of operating temperature ranges, with a minimum of -40°C and maximum of 125°C. The LP2985AIM5-4.7/NOPB is capable of supplying up to 150mA of load current and has a maximum operating voltage of 6V. In terms of its design, the LP2985AIM5-4.7/NOPB is a space-saving, SOT-23-5 package, which measures to 2.92 × 2.92 × 0.90mm.

The LP2985AIM5-4.7/NOPB has a unique feature as well, which is its adjustable turn-on delay time. This allows it to be used in applications where many power regulators are used in close proximity. This is due to its ability to prevent any undesired glitches in the power supply. Furthermore, the LP2985AIM5-4.7/NOPB leverages the Enhanced Load Transient Response (ELTR) technique, which helps maintain its regulation even with large load currents.

The LP2985AIM5-4.7/NOPB has a variety of applications, and is best suited for low-power, low-noise applications. It is designed for applications such as embedded systems, RF power amplifiers, optical modems and industrial battery-driven systems.

The working principle of the LP2985AIM5-4.7/NOPB is fairly straightforward. The integrated circuit comprises of three main components: an error amplifier, a reference voltage source, and a pass element. The error amplifier is responsible for comparing the inputs, and is used to compare the reference voltage with the voltage at the output. Whenever the voltage at the output surpasses the preset value, the error amplifier triggers the pass element, which regulates the current flow and limits the output voltage. This operating principle helps the LP2985AIM5-4.7/NOPB to maintain a constant output voltage even with varying input voltage or load current changes.

The LP2985AIM5-4.7/NOPB offers a reliable, high-performance and cost-effective voltage regulating solution. Its low quiescent current, low dropout voltage and adjustable turn-on delay time make it a great choice for many applications. Furthermore, its compact, SOT-23-5 package is designed to accurately and safely regulate voltage in industrial and automotive applications, as well as embedded systems, RF power amplifiers and optical modems.
