LP8345IDT-5.0/NOPB

Application Field and Working Principle of LP8345IDT-5.0/NOPB

The LP8345IDT-5.0/NOPB is an adjustable linear voltage regulator designed as an ideal solution for low-noise, low-power applications. This product is designed to support a wide range of output voltages, input-to-output offset, and quiescent current, making it suitable for use in a variety of different electronic products. The device is also designed to provide power-saving features to reduce its overall power consumption, as well as protect itself against over-temperature and over-voltage conditions to ensure its longevity and efficient operation in the real-world.

Classification

LP8345IDT-5.0/NOPB is a type of voltage regulator, which falls under the overall category of PMIC (Power Management ICs). This particular device belongs to the voltage regulators group of PMIC, more specifically in the linear voltage regulator group.

Output Voltage Adjustment

LP8345IDT-5.0/NOPB features a wide range of adjustable output voltages (V out ) ranging from 0.8V up to 5.0V with a accuracy of ±0.06V. This makes it suitable for applications with different voltage requirements, allowing it to serve as a power source in electronic devices, such as mobile phones, laptops and various other consumer electronic devices. The user can adjust the output value by changing a single resistor connected to the REF pin.

Input-to-Output Offset

LP8345IDT-5.0/NOPB features an input-to-output offset (V off ) of up to 5V which is higher than most other devices of its kind. This makes it suitable for applications where an input-output offset of more than 5V is required. This feature further reduces risk of high current flow between the input and output, and increases stability of the output voltage, even when there is a sudden change in input voltage.

Quiescent Current

LP8345IDT-5.0/NOPB also includes a low quiescent current (I q ) option, allowing it to consume very low amount of power when in idle mode. This feature helps reduce overall power consumption and extend the battery life of electronic devices. The maximum quiescent current consumption is as low as 15μA which is lower than most other linear voltage regulators on the market.

Protection Features

LP8345IDT-5.0/NOPB features various protection features that protect against over-current, over-voltage and over-temperature conditions. It also includes a Thermal Shut-off Protection that automatically shuts down the device’s operation when the temperature rises too high, helping reduce the potential for damage to the device.

Conclusion

The LP8345IDT-5.0/NOPB by Texas Instruments is an adjustable linear voltage regulator with a wide range of output voltages and input-to-output offsets, a low quiescent current consumption and various protection features that make it suitable for use in various electronic devices. Its adjustable voltage and offset features allow it to be used in applications with different voltage requirements, while its low current consumption and protection features help increase the device\'s reliability and longevity.
