The Texas Instruments LP3873/LP3876 series offers fast ultra low-dropout linear regulators suitable for low voltage microprocessor applications. This specific part, the LP3873ES-1.8, operates from a +2.5V to +7.0V input and provides a fixed 1.8V output voltage with an ensured accuracy of ±1.5% at room temperature. It is designed to respond quickly to load changes and can supply up to 3A of DC current.
Key electrical characteristics include an ultra low dropout voltage, typically 80mV at 300mA and 800mV at 3A. The device features low ground pin current, typically 6mA at 3A load, and a very low quiescent current of 1µA in shutdown mode. Protection features include overcurrent, overtemperature, and short circuit protection. An error flag indicates output status, going low when the output voltage drops 10% below nominal.
The LP3873ES-1.8 is available in a DDPAK/TO-263-5 package, designed for surface mounting. The operating temperature range is -40°C to +125°C junction temperature. This regulator is well-suited for applications requiring stable and efficient power delivery, such as microprocessor power supplies and battery chargers.
