LDLN025J33R Integrated Circuits (ICs)

A linear voltage regulator is a type of DC power supply that helps regulate the output voltage from a device to a needed level, like 5V or 3.3V. The current LDNL025J3R is an ideal example of such a regulator, built for use in a variety of low-power applications.

Features

The LDNL025J3R offers voltage regulation for applications that don\'t require high current capabilities, such as power banking solutions, battery powered devices, and hand-held consumer electronics. It offers low quiescent current and EMI/ripple rejection, making it a good candidate for battery-powered applications. It also features an adjustable output voltage allowing the device to be used in a range of different applications.

Application Field

The LDNL025J3R is used in numerous low-power devices, such as digital cameras and camcorders, handheld radios and GPS units, portable audio player, and other consumer electronics. It can also be used in automotive power management solutions, providing up to 25W of output power.

Working Principle

The LDNL025J3R voltage regulator operates by taking the input voltage and using it to keep the output voltage more or less constant and within the specified range. This is done through a voltage divider and an error amplifier that is placed between the output and reference voltage. When the output voltage deviates from the reference voltage, the error amplifier produces a signal that is then used to adjust the voltage divider, controlling the output of the regulator. This process repeats until the output voltage is within the desired range.

Conclusion

The LDNL025J3R is a linear voltage regulator, designed for low-power applications. It offers low quiescent current and EMI/ripple rejection, as well as adjustable output voltage, allowing it to be used in a range of devices, including digital cameras and camcorders, handheld radios and GPS units, portable audio players, and other consumer electronics. It also operates by utilizing a voltage divider and error amplifier to keep the output voltage more or less constant and within the specified range.
