The L4989MD013TR is a highly efficient high power linear voltage regulator device, developed and manufactured by STMicroelectronics. It is a pMOS band-gap regulator with an adjustable output voltage range, ideal for applications that require a low-noise, low-power solution. The L4989MD013TR is designed to regulate the voltage applied across a load, such as a motor, heating element or other device, to a predetermined and adjustable level. This effectively provides the user with a means to precisely control the output voltage in order to power the device safely and effectively.

When the L4989MD013TR is in use it will take the input voltage and regulate it to an adjustable level that can be set by the user. This adjustable level is measured in the unit of voltage and is called the regulated voltage. The regulated voltage is the desired voltage that the device must maintain while in use and is measured at pin 1 of the device. The L4989MD013TR has an adjustable output voltage range of 1.8V to 3.3V which is set using a single external resistor. This single resistor gives the user the ability to adjust and customize the output voltage to suit their application needs.

The internal circuitry of the L4989MD013TR consists primarily of a pMOS band-gap reference circuit, which is used in combination with an external resistor to determine the regulated voltage. The pMOS band-gap reference circuit is designed to obtain a high accuracy, noise immunity, and a wide temperature range. This combination of features allows the device to have excellent load and line regulation over the full temperature range. Additionally, the device has a current noise reduction circuit which maximizes efficiency and keeps the noise at a minimum.

The primary applications for the L4989MD013TR include some of the most popular consumer electronics devices and appliances such as smartphones, digital cameras, computers, audio equipment, and home automation devices. The L4989MD013TR is also suitable for use in automotive applications such as in-car infotainment systems, safety systems, and power supply systems.

This linear voltage regulator device is highly versatile and offers a wide range of features and benefits. Its low power consumption and wide operating temperature range make it an ideal choice for a wide variety of applications. In addition, its adjustable output voltage range and low noise operation ensure that it is able to deliver stable, consistent power no matter the environment or application. All of these features come together to make the L4989MD013TR an efficient and reliable choice for any system that requires a low-power solution.
