LM385BYMX-2.5/NOPB Application Field and Working Principle

PMIC, or Power Management Integrated Circuit, is designed to manage power through controlling the levels of the voltage and current. One of the components in PMIC is a voltage reference, which is responsible for providing a steady reference voltage regardless of the system load. LM385BYMX-2.5/NOPB is a voltage reference produced by Texas Instruments. This article will discuss its application field and working principle.The LM385BYMX-2.5/NOPB voltage reference is used in a variety of applications, such as automotive, battery-powered systems, and portable electronics. It is extremely small, with dimensions of 2.1 x 2.1 x 0.95 mm. This makes it ideal for use in space-constrained systems. It can also operate under a wide range of input voltages, from 9V to 20V, and its operating temperature range is from -40C to 125C. In addition, it features low dropout voltage as well as a low operating current consumption, which allows for prolonged battery life.The LM385BYMX-2.5/NOPB voltage reference works by maintaining a constant output voltage, regardless of changes in load or input voltage. It consists of an operational amplifier (Op-Amp) and a bandgap reference. The operational amplifier is responsible for monitoring and adjusting the voltage at its output according to the voltage at its input. The bandgap reference produces a reference voltage that is used as a baseline for the output voltage. The voltage reference relies on an adjustable resistor to adjust the output voltage according to the reference voltage.The difference between the output voltage and reference voltage is detected by the operational amplifier and the output voltage of the voltage reference is then adjusted accordingly. This process is continuously repeated to maintain the output voltage of the voltage reference at the desired level. In other words, the output voltage of the LM385BYMX-2.5/NOPB voltage reference will remain constant regardless of any changes in the load or input voltage.The LM385BYMX-2.5/NOPB voltage reference also features a low power consumption level, which makes it great for products that require a low-power voltage reference. This feature is the result of the low-bias current of the voltage reference, which means that the voltage reference requires only a small amount of current to produce its output voltage. Additionally, the LM385BYMX-2.5/NOPB voltage reference is available in a tiny TDFN package.To sum up, the LM385BYMX-2.5/NOPB voltage reference is a great choice for many applications. Its tiny size, wide input voltage range, low power consumption, and low-bias current make it ideal for battery-powered systems. It is also suitable for automotive, portable electronics, and many more applications due to its excellent accuracy and stability.
