Categories: Linear, Low Drop Out (LDO) Regulators
Quality Control: Learn More
Texas Instruments LP3891ET-1-8-NOPB is a fixed output voltage linear regulator IC offering 1.8V at 800mA. This device features an ultra-low dropout voltage of 0.4V at its maximum output current, contributing to efficient power management. The regulator includes comprehensive protection circuitry, encompassing over-current, over-temperature, short-circuit, and under-voltage lockout (UVLO) capabilities. With a quiescent current of 30 µA, it is suitable for battery-powered applications. The component offers a Power Supply Rejection Ratio (PSRR) ranging from 80dB to 65dB across the 120Hz to 1kHz frequency band. It is supplied in a TO-220-5 package for through-hole mounting and is designed for operation within an ambient temperature range of -40°C to 125°C. Typical applications include consumer electronics, industrial power supplies, and automotive systems.
