The MP2126DN-LF is a voltage regulator manufactured by Monolithic Power Systems (MPS). This device is a linear-switching voltage regulator which has been designed as an easy-to-use low-cost solution for power supply designs. It is suitable for powering low-power communication and control systems, such as those found in consumer applications, industrial systems, and automotive systems. This device is an excellent choice for providing the power needed to ensure that all devices are correctly receiving their necessary supply voltages.

The MP2126DN-LF is equipped with output voltage accuracy as low as ±1.5%, a maximum output voltage of 5.5V, and a maximum output current of 2.6A. It also features 1% efficiency with a maximum power dissipation of 0.12 Watts. This device is capable of supplying a clean and regulated voltage to a wide range of loads, including analog and digital circuits, microprocessors and memories, LCD displays, and low-voltage LEDs.

The MP2126DN-LF provides a high level of flexibility and efficient operation with its various features. For instance, its pulse-width modulation (PWM) switching frequency can be adjusted to provide a precise output voltage, even under heavy load conditions. It is also able to operate over a wide input voltage range, from 3V to 15V. In addition, it provides a precise voltage accuracy over line and load changes and matched power dissipation at all load conditions, resulting in excellent regulation performance.

The MP2126DN-LF incorporates several protection features as well. This device is designed with both over-voltage and over-current protection, which provide protection against potentially damaging power surges and other power faults. Additionally, it also features thermal shutdown to protect against abnormally high temperatures. Additionally, it includes frequency synchronization and soft-start circuits, which allow for a smooth transition during power-up and power-down while minimizing power consumption.

The MP2126DN-LF utilizes a buck-boost topology, which allows it to efficiently switch between “buck” (step-down) and “boost” (step-up) modes however, this feature requires an LVRAF (Low-Voltage Reverse-polarity Activation Frequency) external capacitor, which helps to set the PWM switching frequency.

The MP2126DN-LF is an excellent choice for voltage-regulated power supplies for low-power applications. Its integrated features provide high flexibility and reliable operation over a wide input range, line and load changes, and power dissipation, making it an ideal choice for powering a wide variety of devices.
