The LM385BXZ-1.2/NOPB is a voltage reference from the PMIC – Voltage Reference family. It is a voltage reference or a voltage regulator designed to provide a very stable reference voltage of 1.2V over a wide range of current output. It is used when a constant voltage is required without any fluctuations. The LM385BXZ is an thermally stabilized three-terminal adjustable voltage regulator featuring a low temperature coefficient of ±25ppm/°C. This ensures a stable voltage reference with extremely accurate voltage over a wide temperature range of -40°C to +85°C which is perfect for high-accuracy analog and digital applications.

The LM385BXZ-1.2/NOPB is especially designed with a low current drain to allow operation of the regulator using just a few milliamps. This device also features an enable/disable control pin, to control the enable or output state of the device. With an enable pin low, the device is disabled and the output state will be Hi-Z, otherwise if enabled, the output will be connected to the ground pin.

The LM385BXZ-1.2/NOPB uses an internal band-gap reference circuit and it is mainly intended for use in 3-terminal adjustable applications including stand-alone and battery-based systems. It can also be used as a precision shunt regulator in various analog and digital control systems. The device requires very few external components to provide a wide range of output voltage. It has a voltage range of 0.7V to 4.75V with 1V steps on its output voltage.

The working principle of the LM385BXZ-1.2/NOPB is based on the well-recognized band-gap voltage reference. It offers an incredibly low temperature coefficient and an exceptional stability for precision analog and digital applications. The device is designed to work over an operating junction temperature ranging from -40°C to +85°C and offers high accuracy even in extreme temperature ranges. The device uses an internal band-gap reference and a simple three-terminal adjustable architecture to provide a 1.2V output voltage.

In terms of its features, the LM385BXZ-1.2/NOPB offers an exceptional dynamic response to output voltage changes. It also features a high over-temperature protection of 13V, eliminating the need for any external temperature sensing and thermal tracking components. The device includes an enable/disable control pin which allows the user to enable and disable the regulator using the enable pin. Finally, it also offers an enable pin that acts as an enable or open drain output which allows for easy enable/disable control of the device.

Overall, the LM385BXZ-1.2/NOPB from PMIC – Voltage Reference family is an incredibly accurate and efficient device designed for precision analog and digital applications. It offers a wide range of output voltage and a very low current drain allowing the device to be powered by just a few milliamps. Plus, it provides an enable/disable control pin, and a high temperature thermal protection. Thus, it is a perfect choice for use in 3-terminal adjustable applications.
