The LP2986IM-3.3 is a 3.3-volt, low-noise and low-dropout linear voltage regulator (LDO) designed for circuit performance, stability and reliability. It is designed for applications that require minimal quiescent current and low noise. It has extremely low dropout voltage and ultra-low quiescent current, which make it suitable for improved battery life in portable consumer and computing systems. It also features adjustable output voltage from 2.5V to 5.5V, low ground pin current signal, over-current and over-temperature protection, and excellent power supply rejection ratio.

LP2986IM-3.3 is a low-dropout linear regulator that can provide a regulated output voltage of 3.3V with an input voltage range of 2.5V–5.5V. This LDO regulator also features a very low quiescent current, so it is well suited for applications that require long battery life. It can provide a dropout voltage as low as 0.15V at its maximum current capability. In addition, it features ultra-low noise, with a typical noise of only RP (ppm) at the output. For further optimization, the output voltage can be adjusted with the enable pin to adjust the output voltage of the regulator instead of the feedback resistor.

The LP2986IM-3.3 is an ideal choice for a wide range of applications, such as computers, portable devices and industrial equipment. This linear regulator can provide an extremely low quiescent current of only 85µA, which helps protect the battery life of the system. This voltage regulator offers fixed and adjustable output voltage, overload protection, and also offers excellent power supply rejection ratio (PSRR). Therefore, this regulator can be used to reduce power losses and improve power efficiency.

The working principle of the LP2986IM-3.3 is similar to other linear regulators. It uses the voltage difference between its input and output to regulate its voltage. When the voltage at the input side is higher than the desired output voltage, the linear regulator reduces the voltage by drawing current from the load. This current is then converted into a voltage through a pass element, and then it enters the load as the desired output voltage. The output voltage is then determined by the combination of the Voltage Regulation element, the Reference element and the Voltage divider.

The LP2986IM-3.3 linear voltage regulator offers many benefits such as its extremely low dropout voltage and ultra-low quiescent current, high reliability and stability, and adjustable output voltage. It is an ideal choice for applications that require low power consumption and low noise. It can also provide overload protection and improved power supply rejection ratio, which make it a perfect choice for portable consumer and computing systems.
