LP2986IMM-5.0/NOPB is a voltage regulator belonging to the PMIC (Power Management Integrated Circuit) series of Linear Voltage Regulators. This product is developed and manufactured by Texas Instruments (TI). It is designed to provide a stable and regulated 5.0V/400mA output from a wide variety of AC or DC input sources.

The LP2986IMM-5.0/NOPB is a low dropout 3-terminal voltage regulator with a simple output voltage-adjustment range from 4.45 V to 10V. The product has an excellent transient response, a fast line and load-regulation rate and a low dropout voltage of comparable or less than 200mV over full load current range. It also features a total capacitance of just 32 nF, a quiescent current of 18 uA, and a voltage trimmable range of 1.22V over the full operating temperature range.

The LP2986IMM-5.0/NOPB includes ultracapacitor technology that mitigates output voltage droops due to input voltage transients and enables ultra-low dropout operation under light loads. The device also has active current limiting and thermal shutdown to provide protection in the event of over-current or over-temperature conditions.

The LP2986IMM-5.0/NOPB has many applications, including process control, automotive, industrial and home appliances, digital audio/video devices, and point-of-load (POL) voltage applications. It is specifically designed to be used in applications where output current and noise immunity are of paramount importance.

The working principle of the LP2986IMM-5.0/NOPB voltage regulator is fairly simple. The input is connected to a high-gain comparator. This reduces the input voltage to a reference voltage, and amplifies the difference between the two. The amplified signal is then used to control the output voltage.

The output of the comparator is then connected to a current-limiting circuit that prevents excessive current from flowing out of the output. Finally, the current-limiting circuit is connected to an output voltage adjust terminal that allows the user to set the desired output voltage.

The LP2986IMM-5.0/NOPB is an efficient and reliable voltage regulator. It provides a stable 5.0V/400mA output, and is suitable for a wide range of applications. Its comparator-driven output voltage adjuster allows for precise and adjustable output levels, and its ultracapacitor technology provides ultra-low dropout voltage and transient response. Its active current limiting and thermal shutdown protection ensure that the voltage regulator is not damaged due to over-current and over-temperature conditions.
