LDK120C29R

LDK120C29R is a popular linear voltage regulator integrated circuit (IC) from Infineon Technologies AG. It is part of the LDK120 series, and is suitable for applications requiring efficient voltage regulation over a wide voltage range. It is typically used for regulated power for Digital Signal Processor (DSP) cores in automotive and industrial applications.

This linear voltage regulator has a low dropout voltage and a low quiescent current. It also has a wide input range of 3.3V to 30V, and an output voltage range of 0.8V to 28V. The LDK120C29R can achieve up to 5 percent accuracy, as well as a low ripple and noise quality. The device is protected with an on-chip Thermal Shutdown feature to prevent excessive heat buildup that can damage the IC.

Application Field

The LDK120C29R is most commonly used for voltage regulation in automotive and industrial applications. This device is ideal for controlling the power of Digital Signal Processors for applications such as motor control, audio/video, and communications equipment. It can also be used in automotive, consumer, medical, and other high-current applications.

This device is also used in a variety of consumer, automotive, and industrial applications, such as communications equipment, consumer electronics, and audio/video equipment. The LDK120C29R can also be used in automotive applications such as engine control applications, CAN and LIN busses, as well as fuel gauges and ECUs.

Working Principle

The LDK120C29R uses a linear voltage regulation method, which works by regulating the output voltage to a specific value regardless of the input voltage. This is accomplished by controlling the amount of current flowing through an adjustable resistor. As the input voltage varies, the resistance is adjusted to maintain the output voltage at the desired level.

The device is equipped with an on-chip Thermal Shutdown feature which helps to protect the IC from excessive heat buildup that can damage it. The Thermal Shutdown feature shuts down the device when the internal temperature exceeds a specified safe limit. This feature can help protect the device from thermal damage caused by overloading of the LDK120C29R.

Conclusion

The LDK120C29R is a highly versatile linear voltage regulator IC, suitable for a wide range of applications. Its low dropout voltage, wide input range, and precision regulation make it ideal for automotive, industrial, and consumer applications. The device is also equipped with a Thermal Shutdown feature which helps to protect the device from thermal damage caused by overloading.
