PMIC, or power management integrated circuits, are specialized integrated circuits that manage power distribution and generation in increasingly complex electronic systems. The LP3966ESX-2.5/NOPB is a linear voltage regulator designed to provide highly accurate, low-noise power management solutions in a variety of applications.

Application Field and Working Principle

The LP3966ESX-2.5/NOPB is well suited for use in a variety of applications, from consumer and medical electronics to automotive, industrial and embedded systems. Its linear voltage regulation technique ensures low noise power supply and extreme precision when providing output voltages between 1.4 and 21.4V and can provide output currents up to 1.5A at up to 85°C.

The linear voltage regulation approach used with the LP3966ESX-2.5 eliminates the need for additional components to form a voltage regulator circuit. When activated, the LP3966ESX-2.5 automatically adjusts the output voltage to match the input voltage while dissipating heat through a small built-in heat sink. As a result, the device provides better power efficiency and greater reliability than traditional switching-type voltage regulators.

The LP3966ESX-2.5/NOPB is available in a small, surface-mount package and incorporates a host of protection features that provide protection against input and output over-voltage, over-temperature, reverse current and short-circuit conditions. In addition, the LP3966ESX-2.5 includes a soft-start feature that ramps up the output voltage over a predefined ramp time, to reduce inrush current and ensure a smooth start-up. This feature can be disabled if not required.

To further enhance performance and reliability, the LP3966ESX-2.5/NOPB utilizes an internal compensation network, giving the IC the ability to maintain a stable output voltage and current despite manufacturer or environmental variations, without the need for additional external components. The use of low-drop linear regulators allows the device to reduce power loss and save further energy, making it an ideal choice for more compact applications and energy-critical systems.

The LP3966ESX-2.5/NOPB requires a minimum input voltage of 3.5V, and operates over a wide temperature range of -40°C to +85°C. Its highly accurate and stable outputs are further enhanced by the use of current-mode and voltage-mode loop control that helps maintain stability. In addition, the linear voltage regulator includes a range of circuit protection features such as reverse voltage protection, adjustable input current and power-on reset protection.

The LP3966ESX-2.5 stand-alone linear voltage regulator is designed to accurately and reliably provide a wide range of DC voltage levels, on demand and when used in conjunction with additional external circuitry as required. With its superior power efficiency, fast response times and several circuit protection features, the LP3966ESX-2.5/NOPB is an ideal power solution for modern electronics that require highly precise and reliable voltage regulation.
