It is also used in sensor power supplies, wireless power systems, and USB systems.

The LP2985ITLX-3.3/NOPB operates in drop-out mode, which allows it to deliver full output current with as little as 0.5V input-output differential. The device is also capable of delivering accurate and noise-free voltage regulation in the presence of transients and other noise sources. It features low on-resistance to minimize dropout voltage and maximizes the power delivered to the load. Additionally, the device can function at low quiescent current and has a wide operating temperature range from -40°C to 85°C.

The LP2985ITLX-3.3/NOPB uses a proprietary error amplifier comprised of a low phase-noise low-noise voltage reference and a CMOS error amplifier. The voltage reference is set to a nominal 2.5V, and is designed for low noise and fast transient response. The error amplifier is designed to provide the output voltage with its full range of accuracy, linearity and low drift. The combination of the error amplifier and its low phase-noise reference make the LP2985ITLX-3.3/NOPB suitable for use in wideband applications, such as communication systems.

The LP2985ITLX-3.3/NOPB uses a current-mode regulating mechanism. This method of regulation provides superior line and load rejection, fast transient performance and stable oscillations over wide temperature ranges. The current mode regulation technique allows the device to react quickly to any changes in the output characteristics or load conditions. Furthermore, the device is capable of compensating for process variations, temperature fluctuations, and factory test conditions.

The LP2985ITLX-3.3/NOPB provides excellent output voltage accuracy and is designed to maintain low output voltage noise.
