LDL112PU12R Application Field and Working Principle

LDL112PU12R is a voltage regulator, part of the PMIC (Power Management Integrated Circuit) family that is widely used in a variety of applications and related products. This regulator can provide a wide range of output current and load capability, making it suitable for applications with high voltage requirements.

LDL112PU12R is a linear voltage regulator, a type of low dropout regulator (or LDO) that operates with a relatively low dropout voltage or ‘headroom voltage.\' It consists of two metal-oxide-semiconductor field-effect transistors (MOSFETs), which operate in a typically fixed voltage mode, providing a well-regulated output voltage that remains stable even when the input voltage changes. It is usually used to create an output voltage between 1.2V and 12V.

The typical input voltage range of the LDL112PU12R is 3V to 36V. Its output voltage can be adjusted with a single resistor, allowing it to supply either a fixed voltage or to respond to an external voltage reference, making it an ideal choice for low to medium current regulation applications. With a wide adjustment range, it is also suitable for powering high current/high voltage loads or for providing a regulated single cell Li-Ion battery charger.

The LDL112PU12R is capable of providing a regulated output voltage in the range of 0.7V to 12V, with an efficiency rating of up to 97% while in operation. Its low minimum dropout voltage of as low as 0.5V allows the regulator to maintain a relatively high output current and a low quiescent current of 6.5 µA (microamps). Its over-current protection feature is also beneficial for the prevention of damages due to excessive current flow.

LDL112PU12R can find application in a wide range of power supply and voltage regulation systems, including consumer devices such as laptop computers and cell phones. This efficient and reliable linear voltage regulator can also be used in industrial applications such as industrial control systems, as well as in automotive and home applications.

LDL112PU12R is able to provide a wide range of features, making it an ideal choice for use in a broad range of applications. It is lightweight and capable of providing excellent thermal handling and temperature stability, providing a stable and reliable operating performance. Additionally, its wide range of operating temperature (from -40°C to 85°C), enables it to be used in a variety of environmental conditions.

In conclusion, LDL112PU12R is an efficient and reliable linear voltage regulator that is suitable for powering a variety of applications and systems. Its low headroom voltage, low quiescent current, and high efficiency rating make it an ideal choice for use in a wide range of applications.
