Introduction to LP8340CDT-1.8/NOPB

LP8340CDT-1.8/NOPB is a voltage regulator belonging in the PMIC – Voltage Regulators – Linear category. It is an adjustable linear regulator with an adjustable output of from 0.8Volts to 5.5Volts. It is an external component that is used to maintain a steady voltage level for a wide variety of applications. Its application field includes systems that require a regulated supply of current, including mobile phones, cameras, audio systems, tablets, and many other types of digital devices.

Application Field and Working Principle of LP8340CDT-1.8/NOPB

LP8340CDT-1.8/NOPB can adjust the output voltage to any value between 0.8Volts and 5.5Volts, depending on the designer or application need. This versatile, fully adjustable controller can be used to replace discrete linear regulators, as well as other adjustable voltage regulators. The power dissipation is low, making it suitable for many applications where board space is at a premium.

The voltage regulator features an enable/shutdown function which allows the output voltage to be quickly disabled, minimizing the battery drain from an unused circuit. The enable/shutdown pin has a hysteresis of 800mV which allows it to be used as a “window comparator”. The output voltage can be adjusted using an external resistor divider or with two external resistors.

The LP8340CDT-1.8/NOPB operates in two distinct power saving modes. When the current drawn from the output voltage decreases, the regulator enters the Supply Follower Mode. In this mode, the regulator reduces the power dissipation by reducing the current though the regulator and thus reducing the output voltage ripple. The second power saving mode is the Hi-Z mode. When no load is connected to the output, the regulator switches to this mode, where the current consumption of the regulator is greatly reduced. This mode also helps to reduce output voltage ripple.

LP8340CDT-1.8/NOPB has several features which make it attractive for many applications including: high power supply rejection ratio (PSRR), low noise, fast transient response, and low dropout voltage. It also has a good load regulation, and thermal overload protection. The maximum output current of the regulator is 330mA, which allows it to be used in a wide range of applications.

Conclusion on LP8340CDT-1.8/NOPB

LP8340CDT-1.8/NOPB is a highly efficient, fully adjustable linear voltage regulator designed for applications that require a regulated power supply. Its adjustable output and low power dissipation make it an ideal choice for applications such as mobile phones, cameras, and audio systems. The voltage regulator offers excellent PSRR and load regulation and can be adjusted with the use of an external resistor divider or two external resistors. Its two power saving modes, Shuttle Follower Mode and Hi-Z Mode, further increase the efficiency of the regulator, making it a great choice for today’s applications.
