LP2985AITPX-2.5/NOPB

The LP2985AITPX-2.5/NOPB is a low drop-out linear voltage regulator that is part of the Texas Instruments Power Management integrated circuit (PMIC) family. This device is specifically designed for use as a voltage regulator in many different applications as it is highly efficient, reliable, and cost-effective.

This device has a wide input voltage range of up to 8.4–36V and is available in a space-saving, 3 mm × 3 mm 10-pin package. It is rated for a maximum load current of up to 250 mA and features a low dropout voltage of 200 mV. Its temperature range is from −40 °C to +125 °C, and its junction temperature is maximum +150 °C. It also features a wide output voltage range up to 2.5V.

The LP2985AITPX-2.5/NOPB has a variety of advantages over other power management ICs, including the use of an LDO regulator. An LDO regulates the output voltage using a loop that tracks the input voltage and adjusts the voltage accordingly. LDOs are much more efficient than switching regulators, with efficiencies reaching 90% or greater. Additionally, they generate low levels of so-called EMI noise compared to switching regulators, making them suitable for many noise-sensitive applications.

The LP2985AITPX-2.5/NOPB has been specifically designed for use in applications such as low power system on-chip voltage regulation, point-of-load voltage regulation, and post-regulator applications. It also integrates an array of protection features, including thermal shutdown, under-current detection, output over-current protection, and output over-voltage protection, that help ensure its safety and long-term performance. The device keeps its power efficiency high even when its switch is OFF, which helps reduce power consumption and make the device more efficient overall.

In addition, the LP2985AITPX-2.5/NOPB has a high PSRR (Power Supply Rejection Ratio) of up to 77dB at 100 kHz, which ensures that any noise or fluctuations in the power supply are filtered out, allowing for clean and reliable voltage regulation. The device also features low quiescent current of typically 10 μA, making it suitable for battery-powered applications.

Overall, the LP2985AITPX-2.5/NOPB is an ideal choice for a wide range of applications requiring a low drop-out linear voltage regulator. This highly versatile and efficient device offers a number of benefits, including a wide input voltage range, low dropout voltage, high efficiency, and various protection features, making it a great choice for many applications.
