PMIC—Voltage ReferenceThe LM285M-2.5/NOPB is a member of the LM285 family of voltage references designed and manufactured by Texas Instruments. Voltage references are an important component in many electronic circuitry, regulating the flow of electrical currents and maintaining a desired level of voltage for proper functioning and stability.A voltage reference designates a definite output voltage when its input is subject to varying environmental conditions and fluctuations. The LM285M-2.5/NOPB is a precision voltage reference device that performs this task with high precision and accuracy. It uses a similar circuit as a typical operational amplifier, but functions as a voltage reference instead.The LM285M-2.5/NOPB features a maximum error tolerance of 0.1% over the recommended operating temperature of -40°C to +125°C. It also includes a built-in hysteresis loop between 0.5-1.5V to guarantee stable output voltage over temperature changes and current fluctuations. The device operates on single or dual supplies, and it can be operated over a wide range of current (3V to 20V).The LM285M-2.5/NOPB is designed to work in a wide range of applications, from automotive to industrial and from telecom to medical. The device is suitable for use in battery-operated electronic products, and is also used for precision voltage reference circuits such as high-precision ΔV/Δt and tachometers, active filtration, A/D conversions, and high-precision power supplies.The LM285M-2.5/NOPB features a TO-92 packaging, which allows it to be integrated into a wide range of systems and applications. Its small size allows it to easily fit in high-density circuits, and its high-temperature range allows it to operate in extreme temperature conditions.The working principle of the LM285M-2.5/NOPB is similar to that of an operational amplifier. It contains three stages of circuit operation—an amplifier stage, an error amplifier stage and a reference stage. The output voltage of the voltage reference is determined by the voltage drop across the resistor R1. When the output voltage falls below the reference voltage Vref, the error amplifier increases its gain to correct the output and bring it back to the set point.The voltage reference also includes thermal protection, which prevents the device from overheating and eventually damaging itself. The thermal protection works by shutting off the circuit in case of an excessive rise in temperature. This also helps to extend the life of the device and protect it from damage.The LM285M-2.5/NOPB is an advanced voltage reference design that has been engineered for advanced industrial and medical application fields. It offers high accuracy and low cost, making it well-suited for use in precision circuits and other devices. Its small size, light weight, and wide temperature range make it ideal for a wide range of applications.
