The LM4040QAIM3X2.5/NOPB is a precision voltage reference that belongs to the class of PMIC – Voltage References. It is a low-dropout bandgap 1.25V Voltage Reference device, that has very low temperature drift, good line and load regulation, and excellent long-term stability. This device is especially suitable in voltage reference applications such as light-control and environmental monitoring systems, as well as precision on-board references.

The LM4040QAIM3X2.5/NOPB consists of an adjustable voltage reference core and a low-dropout voltage regulator. The reference configuration uses a trimmed bandgap topology to achieve a low-drift voltage reference output voltage. The adjustable voltage regulator is designed to provide a low-dropout voltage reference source that can drive a load current up to 85mA. The device requires an un-regulated input voltage that is greater than the output voltage.

The LM4040QAIM3X2.5/NOPB features a maximum temperature drift of 20ppm/V, a maximum line regulation of 0.7ppm/V, and a maximum load regulation of 1.2ppm/V. The device also has a maximum output voltage accuracy of 0.2%, with a maximum output current of 85mA. Furthermore, the LM4040QAIM3X2.5/NOPB has excellent long-term stability, with an output voltage drift of less than 5ppm/V.

The LM4040QAIM3X2.5/NOPB has several applications in various fields, including light-control and environmental monitoring systems. The device is also used in precision on-board references, all types of reference voltage applications, and test and measurement equipment. The device is ideal for applications requiring very low drift and excellent line and load regulation.

The operation of the LM4040QAIM3X2.5/NOPB is simple: a voltage greater than the output voltage is applied to the device, and the regulated output voltage is determined by the reference voltage. The output voltage is controlled by an internal voltage reference, which is trimmed in production. The output voltage can then be adjusted by setting an external resistor or digitally via the SPI interface.

The LM4040QAIM3X2.5/NOPB is designed for maximum flexibility, with a wide operating range from 1.5V to 3.6V and a wide output voltage range from 0.5V to 2.5V. The device is also designed to be highly efficient, with a low quiescent current of 15mA, and a high power-on reset threshold of 1.0V.

To conclude, the LM4040QAIM3X2.5/NOPB is a precision voltage reference that belongs to the class of PMIC – Voltage References. It is a low-dropout bandgap 1.25V Voltage Reference device, that is ideal for applications requiring very low drift and excellent line and load regulation. The device is especially suitable in voltage reference applications such as light-control and environmental monitoring systems, as well as precision on-board references. The device is also used in all types of reference voltage applications, and test and measurement equipment.
