The LP2985ITPX-2.8/NOPB is a low dropout regulator specifically designed for portable operating systems. It is a member of the LP2985 family of linear regulators from Texas Instruments. The LP2985ITPX-2.8/NOPB is a fixed output, low drop-out (LDO) voltage regulator capable of supplying up to 250mA of continuous output current, with an input to output differential of only 1.8V over a wide range of output voltages. The device is housed in a tiny 4-pin VSSOP (Very Small-scale Outline Package) package and is capable of regulating input voltages from 2V up to 5.5V.

The typical output voltage of the LP2985ITPX-2.8/NOPB is 2.8V, with a maximum output voltage of 3.3V. It also has a wide operating temperature range of -40°C to +125°C and also features load regulation of 0.2%. It also includes under-voltage protection, reverse current protection and thermal shutdown for enhanced reliability. Overall, the LP2985ITPX-2.8/NOPB is an ideal regulator for use in low power and portable applications where high efficiency and low output voltage noise are required.

The LP2985ITPX-2.8/NOPB features a three-terminal linear regulator which uses a PNP bipolar device as its active element. This regulator operates in a fixed output voltage mode. The output voltage is regulated as long as the input voltage is higher than the output voltage plus the dropout voltage. The input voltage must always stay within the fixed operating range of 2V to 5.5V. The device is designed to be thermally and overload protected.

At the heart of the LP2985ITPX-2.8/NOPB is a high-performance, low-dropout linear regulator circuit which is designed to minimize the external parts count, which significantly reduces the size and cost of the end product. The device requires minimal external components. The device also offers improved transient response, making it ideal for applications with high output interrupt load current. Additionally, the device is available in extended temperature range and is pin-to-pin compatible with the LP2985ITR-2.8/M and LP2985ISR-2.8/UM model devices.

The LP2985ITPX-2.8/NOPB is widely used for applications such as boot loading microprocessors, digital power management, battery backup systems, portable devices, and small current monitoring. It is also suitable for applications where efficiency is critical, such as digital cameras, cellular base stations, and digital televisions.

In conclusion, the LP2985ITPX-2.8/NOPB is a versatile and cost-effective linear regulator that provide accurate and noise-free output voltage regulation. With its low dropout voltage, wide input voltage range, and low output voltage noise, the LP2985ITPX-2.8/NOPB is ideal for low power, portable, and low current monitoring applications.
