LM285DRG4-1-2

PMIC (Power Management Integrated Circuit), is used to control the power distribution in a circuit, and it has a wide range of applications in the industrial, automotive and consumer electronics industry. An important subgroup of the PMIC family is the Voltage Reference, which refers to integrated circuits that are used to accurately maintain a stable voltage level. One of these voltage references is the LM285DRG4-1-2, which is a monolithic integrated circuit for providing stable and accurate references for use in a variety of applications including process control, communication, frequency regulation and medical systems.

The LM285DRG4-1-2 is a low-power, temperature compensated voltage reference, capable of maintaining a regulated voltage over a wide range of temperature and input voltage variation. The device is available in an SOT23-3, SOT-23-6 and MSOP-8 package, with a wide operating temperature range of -40 to +125 degrees Celsius. It features 1.2V output voltage with an input voltage of up to 5.5V and an output current of 350mA.

The LM285DRG4-1-2 has a wide range of applications due to its robust and accurate reference voltage circuitry. The device is ideal for analog-to-digital (ADC) applications, as the error margin of the reference voltage ensures that the input signal is converted correctly and accurately. The device is also well suited for use in power converters, which draw the necessary power for their operation from the reference voltage. In addition, the reference voltage can be used for the calibration of DC circuits and sensors, as the stable and accurate reference voltage ensures the optimal performance of the device.

The working principle of the LM285DRG4-1-2 is based on a combination of an implementation of internal temperature compensating circuitry. This circuitry is used to actively correct the voltage reference, which enables the device to reduce both short-term and long-term drift in the reference voltage. This is because the circuit has to adjust its reference voltage to compensate for temperature variations. The internal resistors and capacitors have been selected and activated to provide the required temperature coefficient. The device also incorporates a voltage trimming circuit to allow for accuracy calibration.

The LM285DRG4-1-2 is an ideal solution for providing an accurate, stable and robust reference voltage in a wide range of applications, from process control to medical systems. Its ability to maintain the reference voltage over a wide range of temperatures and input voltage variations makes it ideal for many industrial and automotive applications, while its low-power profile ensures that it is well suited for use in portable and battery-powered devices as well.
