The SPX2431AM-L/TR is a voltage reference chip from NXP Semiconductors (formerly Philips Semiconductors). This is a 3-terminal adjustable voltage reference designed to allow the user to adjust the output voltage over a wide range of output voltage. The SPX2431AM-L/TR is part of the family of NXP ICs that feature a low temperature coefficient of 0.007 percent versus a temperature operating range of –40°C to 85°C. This device is ideal for applications requiring adjustable voltage, low temperature coefficient, and low current consumption.

The SPX2431AM-L/TR is a PMIC (power management integrated circuit) intended for use in low-power applications. It operates over a wide range of input and output voltages, and provides a low-temperature coefficient output current that is suitable for use in a variety of battery-operated or low-power systems. It can operate with a supply voltage as low as 1.2V and a voltage reference as low as 0.6V.

The device is based on a bipolar approach and offers excellent accuracy due to its precision, low temperature drift and low current consumption. The SPX2431AM-L/TR also features a fast transient response and excellent line regulation. The SPX2431AM-L/TR also features excellent current regulation and is capable of producing a highly regulated output voltage.

The output voltage of the SPX2431AM-L/TR is defined by two resistors, an adjustable resistor and a fixed resistor. The adjustable resistor is used to adjust the output voltage over a wide range. The output voltage is simply a function of the ratio of the two resistor values. The adjustable resistor is connected to the ADJ pin, and the fixed resistor is connected to the GND pin. The ground and VIN pins should be connected to a high-impedance resistor.

The operating principle of the SPX2431AM-L/TR is similar to that of a zener diode. The output voltage is determined by the voltage drop across the internal P-N junction diode. This voltage drop is in turn determined by the current flowing through the device. The SPX2431AM-L/TR thus provides an adjustable voltage reference by changing the amount of current flowing through the device.

The SPX2431AM-L/TR is suitable for a wide variety of applications, including temperature sensors, over-voltage protection, shunt regulators, current limiter circuits, voltage references, switch-mode power supplies, sound system circuit correction circuits and memory card circuit protection. In addition, the device is also suitable for use in various optical and consumer electronic systems.

The SPX2431AM-L/TR is a versatile and economical device, allowing the user to easily adjust the output voltage over a wide range. Its low operating temperature coefficient and low current consumption make it an ideal choice for low-power systems.
