The LP2985AIBPX-2.5/NOPB is a micro power voltage regulator that\'s been designed to provide small size and rail-to-rail outputs. This family of linear voltage regulators is available in an easy-to-use small 3-pin SOT package and offers very good accuracy in output voltage, current limiting and thermal protection. With a guaranteed output overvoltage protection and very low supply current, it is ideal for reliable, portable and battery powered system design.

Application Field

The LP2985AIBPX-2.5/NOPB can be applied in professional, medical and industrial solutions. Its use in automation and instrumentation applications, wherein the adjustable voltage ranges from -8.00V to +4.00V, makes it suitable in many applications. For example, it can be used to power tiny and low power sensors, instruments, and measurement equipment. It is also useful to support wireless transceivers and remote power solutions such as personal area network (PAN) solutions. The device can also be used as a negative voltage regulator and power supply source in battery-operated systems.

Working Principle

The LP2985AIBPX-2.5/NOPB is a three-terminal, programmable, linear voltage regulator that operates off a single polarity power supply. It incorporates a power transistor that offers adjustable current limiting, thermal shutdown, and current foldback for protection. This control topology provides excellent stability across line and load variations, thus allowing it to operate without the need for external loop compensation components.

The device offers easy programmability, via programming pins, to adjust the output between the device’s -8.00V to +4.00V range. An integrated NPN power transistor facilitates rail-to-rail load swings without the need for any external components. This makes the device capable of sourcing and sinking up to 150mA of load current. The device is stable up to 1 MHz of small-signal bandwidth and has an output voltage accuracy of 1.3%. The device can also operate at temperatures between -40 oC and +125 oC.

The LP2985AIBPX-2.5/NOPB is also equipped with a wide number of additional features such as high-speed transient response,Disable/Enable controls, higher input voltage capability, low quiescent current, and low Dropout Voltage (DOV) performance. It boasts a wide range of product options to meet various design needs, including options with integrated power shut-down and an adjustable current limit.

Conclusion

As a system design solution, the LP2985AIBPX-2.5/NOPB has been designed to provide a very small size, easy programming, and excellent reliability. Its ultra-low quiescent current and wide range of adjustable voltage make it suitable for use in a variety of applications. Its excellent and effective control topology ensures stable operation across line and load variations, while its integrated power transistor and rail-to-rail load swings make it ideal for battery powered devices. Although the device is cost-effective, features, and providing good output accuracy, its impressive low current dissipation helps minimize system design’s running cost.
