PMIC (power management integrated circuits) voltage regulators are among the most popular components in the power management industry today. The LD39015M18R is a linear voltage regulator, and this article will look at its application field and working principle.

Application Field of LD39015M18R

The main application of the LD39015M18R is in power management. It is used to regulate and control the voltage output of a power supply to ensure that the output from the power supply remains stable and within spec. The LD39015M18R can also be used as a current limiter to protect downstream circuits from damage caused by overcurrent, and as an voltage attenuator to ensure that the output voltage remains within range.

The LD39015M18R is designed for use in a variety of applications, including industrial, automotive, mobile, LED lighting and audio/video equipment. It is also suitable for use in embedded systems, computers, networking equipment and consumer electronics.

Working Principle of LD39015M18R

The LD39015M18R is a low-dropout linear voltage regulator. It uses the source output voltage to regulate the output voltage by monitoring the voltage on the output pin and adjusting the voltage gain of its internal voltage regulation loop until the output voltage matches the target voltage. The LD39015M18R also features a built-in current limiter and over-voltage protection. This allows it to regulate the output voltage over a wide range of output currents and over-voltage conditions.

The LD39015M18R has two internal control tracks: one for voltage regulation and one for current limiting. The voltage regulation track monitors the output voltage and adjusts its voltage gain to ensure the output voltage remains within the specified range. The current limiting track monitors the input and output voltages and adjusts the current limit point accordingly.

The LD39015M18R also features an external amplifier and a soft-start circuit. The external amplifier allows the user to adjust the current limit point, while the soft-start circuit allows the output voltage to gradually ramp up to its target voltage, thus reducing the inrush current. This feature reduces the risk of damage to downstream circuitry caused by excessive current.

In addition, the LD39015M18R has a built-in thermal protection circuit that shuts down the device in the event of an over-temperature condition. This feature ensures that the device does not become damaged due to excessive temperatures.

Conclusion

The LD39015M18R is a low-dropout linear voltage regulator used in a variety of power management applications. It features a built-in current limiter, soft-start circuit and thermal protection circuit. It is suitable for use in industrial, automotive, mobile, LED lighting and audio/video equipment. It is also suitable for use in embedded systems, computers, networking equipment and consumer electronics.
