The L4931CD120-TR is a voltage regulator that belongs to the "Linear" category of power management ICs (PMICs). This type of regulator is used to maintain a steady voltage level on a circuit, and provides a consistent output despite any changes in the input voltage or current. The design of the L4931CD120-TR is particularly well-suited for use in a wide variety of applications in both consumer and industrial electronics.

Application Fields

As a linear voltage regulator, the L4931CD120-TR can be used in a variety of application fields, ranging from consumer electronics to industrial and automotive applications. In consumer electronics, the device is used to maintain the stable operating voltage levels needed to run a variety of low-power electronic applications, such as radio receivers and digital cameras. In industrial settings, the device is often used to provide a steady supply of voltage for potential applications such as motion control and servo systems.

The L4931CD120-TR is also used in automotive applications. In particular, it is very well-suited for use in controlling the output voltage of powertrain components, such as the battery, starter, and alternator. In addition, it is also often used in direct current (DC) motor control circuitry, controller area networks, and a variety of other automotive control systems.

Working Principle

The L4931CD120-TR is a type of linear voltage regulator, which means that it works by precisely controlling the amount of current allowed to pass through it. It does this by comparing the actual voltage level on the input side of the device to a predetermined reference voltage, which is usually set to the desired output level. If the actual input voltage is higher than the reference voltage, the regulator will reduce the amount of current flowing through the device until the correct voltage is achieved.

The exact input/output characteristics of the L4931CD120-TR varies depending on the specific application. The device is capable of providing up to 1.2 watts of continuous output power, with an input range of 3V-18V and an output range of 2V-16V. It also features a 500mA maximum current rating and a max operating temperature of 85°C.

The L4931CD120-TR also features advanced safety protection features, including reverse polarity and over/under voltage protection. These features help to ensure that the device is not damaged by unexpected voltage fluctuations on the input side of the device.

Conclusion

The L4931CD120-TR is a highly flexible linear voltage regulator that is suitable for use in a variety of applications, from consumer electronics and industrial systems to automotive applications. Its wide range of features and safety protections make it an ideal choice for any application that requires a reliable and consistent supply of voltage.
