Texas Instruments LP3881ET-1-5-NOPB is a fixed 1.5V positive linear voltage regulator. This device delivers 800mA output current with a low dropout voltage of just 0.16V at 800mA. It features an enable pin for power sequencing and control, alongside robust protection mechanisms including over-current, over-temperature, short-circuit, and under-voltage lockout. The quiescent current is a low 30µA, making it suitable for power-sensitive applications. With a high Power Supply Rejection Ratio (PSRR) ranging from 80dB down to 65dB across the 120Hz to 1kHz frequency band, it effectively filters noise. The TO-220-5 package with formed leads is designed for through-hole mounting. This component is utilized in industries such as telecommunications, industrial automation, and consumer electronics requiring stable and efficient power regulation. Operating temperature range is -40°C to 125°C.
