The Texas Instruments LP3891ES-1.8 is a high-performance linear voltage regulator designed for various power management applications. It provides a stable, fixed 1.8V output voltage with a maximum output current capability of 800mA. This device features a low dropout voltage of 0.4V at 800mA, making it suitable for low-voltage applications where efficiency is critical.
The regulator operates from an input voltage range of up to 5.5V and includes essential protection features such as over current, over temperature, short circuit, and under voltage lockout (UVLO). Its quiescent current is typically 30 µA, contributing to power efficiency in battery-powered devices. The PSRR (Power Supply Rejection Ratio) ranges from 65dB to 80dB across a frequency band of 120Hz to 1kHz, ensuring clean power delivery.
Designed for surface mounting, the LP3891ES-1.8 comes in a TO-263-6, D²Pak package, facilitating integration into compact electronic designs. The operating temperature range is -40°C to 125°C, allowing for reliable performance in demanding environments. This component is ideal for applications requiring a dependable and efficient voltage regulation solution.
