LP8345ILD-5.0/NOPB

Introduction:

LP8345ILD-5.0/NOPB is a standard linear regulator integrated circuit (IC). This low dropout (LDO) voltage regulator is designed to provide a regulated output voltage of up to 5.0V and is ideal for applications such as cellphone chargers and USB regulators.

Application Field:

LP8345ILD-5.0/NOPB is mainly used for low-noise, low-dropout voltage regulation in forward, reverse or bidirectional configurations. This type of voltage regulator is typically used in applications such as cell phone chargers, radios and USB regulators. Its low-noise design also makes it ideal for other consumer devices such as audio amplifiers and digital audio systems.

Working Principle:

The LP8345ILD-5.0/NOPB is a linear low dropout (LDO) regulator. It has a programmable, adaptive current limit and thermal protection features. When the input voltage is lower than the adjusted output voltage, the voltage regulator will start to deliver current up to the maximum output current limitation. As the output current increases, the voltage regulator will automatically adjust the output voltage to avoid output voltage overvoltage. In the meantime, the device will also protect itself as well as the load circuit from overtemperature.

The LP8345ILD-5.0/NOPB is designed to be used in forward or reverse configurations. It can be used as a current regulator or a power supply. The adjustable current limit can be programmed with the use of external resistor. The hysteresis of current limit is adjustable as well. The over-temperature protection can be enabled or disabled with the use of an external pin which is pulled high for enabling the protection.

Conclusion:

In conclusion, the LP8345ILD-5.0/NOPB is a low noise, low dropout voltage regulator ideal for applications such as cell phone chargers and USB regulators. It features a programmable current limit, adjustable hysteresis, and over-temperature protection. This type of voltage regulator is designed to be used in forward or reverse configurations and is a popular choice for consumer devices such as audio systems and digital audio amplifiers.
