Linear voltage regulators are electrical devices that are used to limit or control the output voltage of a power supply in order to prevent damage to downstream devices. The MIC5239-1.8BM-TR is an example of such a device. It is a three-terminal voltage regulator designed to provide an adjustable output voltage of up to 1.8V with an input range of 0.8V to 17V. It is designed to provide a highly accurate, low-noise, low-dropout (LDO) output voltage with excellent line and load regulation characteristics.

The MIC5239-1.8BM-TR incorporates many features that make it an ideal choice for a variety of applications. As an LDO regulator, it is capable of supplying up to 100mA of output current, allowing it to be used in applications such as battery-powered devices. It has a low quiescent current of 2µA, making it ideal for power-sensitive applications. In addition, its load regulation is 10mV, making it suitable for applications that require very precise voltage regulation. It also features current overload protection, short circuit protection, and over temperature protection.

In addition to power protection, the MIC5239-1.8BM-TR also provides excellent noise suppression characteristics. It has a very low output impedance of 180m?, allowing for enhanced noise reduction. Furthermore, its output voltage is adjustable from 0.8V to 1.8V with a single external resistor, allowing for further flexibility in applications. With its wide input voltage range, the MIC5239-1.8BM-TR can be used in both low-voltage and high-voltage applications, making it an ideal choice for many different applications.

The MIC5239-1.8BM-TR operates by converting the input voltage (VIN) to a regulated output voltage (VOUT). The input voltage is compared to an internal reference voltage (VREF), and an error amplifier establishes a voltage differential between the two. This differential is then amplified to create the necessary control signal to operate an internal p-channel MOSFET. This MOSFET is used in series with a series resistor to form a voltage divider, and is used to set the output voltage. The current flow through the MOSFET is controlled by a PWM controller, and is adjusted according to the input voltage to maintain a constant output voltage.

The MIC5239-1.8BM-TR is a small, highly-efficient voltage regulator suitable for a wide variety of applications. It provides an adjustable output voltage of up to 1.8V, an input voltage range of 0.8V to 17V, an excellent load regulation of 10mV, and a low-noise output impedance of 180m?, making it suitable for power-sensitive applications. In addition, it offers current overload protection, short circuit protection, and over temperature protection. With its wide input voltage range and adjustable output voltage, the MIC5239-1.8BM-TR is an ideal choice for many different applications.
