LDK120C35R Application Field and Working Principle

LDK120C35R is an adjustable linear voltage regulator integrated circuit (IC) belonging to PMIC (Power Management IC) – Voltage Regulators – Linear category. This regulator offers low dropout voltage and low temperature coefficient. Featuring internal current limiting and thermal shutdown, the LDK120C35R is short circuit protection. The output voltage can be adjusted from 1.2V to 35V.

Application Fields

The LDK120C35R has a wide range of applications. It can be used in many industrial, electrical and electronic applications, including DSPs, microcontrollers, digital signal processors, computer and automotive applications, for example. It is particularly useful for battery-powered applications as it provides constant supply current. It can also be used in voltage sensitive circuits, providing adjustable voltage new reference to provide a stable voltage supply rail.

Working Principle

The LDK120C35R typically works by utilizing the differences in device voltages. It features two main components, the main supply (VIN) and the regulated voltage (Vout). The VIN is the power supply that provides the voltage to the regulator. The Vout is the output voltage of the regulator. A difference between VIN and Vout is created by the linear regulator and is referred to as the dropout voltage. The dropout voltage is the difference between the input and output voltage of the regulator, and can range from 0.5 V to 1.5 V. The LDK120C35R is an adjustable voltage regulator and this can be adjusted from 1.2V to 35V. It does so by adjusting the range of the shunt regulator. The regulator consists of three main components; a regulating circuit, an operational amplifier, and a voltage reference. The regulating circuit is responsible for controlling the output voltage and the operational amplifier is responsible for maintaining a constant output voltage. The voltage reference sets the reference voltage of the system and is used as the reference voltage output of the regulator. The operation of the LDK120C35R can be further understood by understanding the role of the feedback loop. The feedback loop takes the output voltage and compares it to the reference voltage. If the output voltage is lower than the reference voltage, a voltage output will be sent back to the regulating circuit to increase the output voltage. This process is repeated continuously to maintain a constant output voltage. In conclusion, the LDK120C35R is a versatile adjustable voltage regulator belonging to PMIC – Voltage Regulators – Linear category. It offers low dropout voltage, low temperature coefficient and short circuit protection. Thanks to its wide range of applications and adjustable output voltage, the LDK120C35R has become a popular voltage regulator for many applications. It is a reliable and efficient way to provide a steady and constant supply of voltage.
