LP2986IMX-3.3 Application Field and Working Principle

Linear voltage regulators, such as the LP2986IMX-3.3, are circuits that maintain a stable output voltage over a range of input voltages and changes in input current. This type of voltage regulator is available in both adjustable and fixed output voltages and is suitable for use as a voltage regulator for many applications including microprocessors, interfacing with analog-to-digital and digital-to-analog converters, and providing bias power for large scale integration (LSI) circuits, portable computers, small medical devices and many other applications.

The LP2986IMX-3.3 is a low drop-out (LDO) positive voltage regulator that provides a 3.3V output at up to 500 mA of output current at an input voltage greater than the output voltage. The LP2986IMX-3.3 has a high efficiency and low noise performance. It can also maintain up to about 90% line regulation for input voltage variations up to 40V.

The LP2986IMX-3.3 is a three-terminal, adjustable, low drop-out (LDO) regulator. It uses an energy-efficient, ultra-low on-resistance, internal P-channel MOSFET pass transistor as a switch, providing excellent current handling and very low output voltage drop at high currents. It features a fast recovery current limit circuit and a programmable stand-by current, which provides excellent thermal and voltage protection without degrading the overall performance.

The operational principle of the LP2986IMX-3.3 is based on the fact that the feedback voltage at the FB terminal (the reference voltage) is regulated to match the output voltage. When the output voltage drops, the greater voltage drop across the internal series pass element causes the voltage at the FB terminal to increase, causing more current to flow through the pass element. This increases the output voltage, allowing it to return to its set point. The FB terminal is internally connected to the output of the regulator, allowing the regulator to respond quickly to changes in the output voltage.

The LP2986IMX-3.3 also includes protection features such as output short-circuit protection, reverse-bias protection, over-temperature protection, and current limit protection. Its shutdown mode offers a very low quiescent current and dropout voltage, making the device an ideal choice for low-voltage and battery-powered applications.

By regulating the voltage of the current supply, the LP2986IMX-3.3 provides power to small, portable devices used in a variety of applications. These include general-purpose appliance control, printing and display driver circuitry, high-performance computing and audio systems, embedded systems, instrumentation, and telecommunication applications. It is widely used in industrial, automotive, and consumer industries.
