Texas Instruments LP3891ET-1-5-NOPB is a fixed 1.5V positive linear voltage regulator IC. This component delivers a stable 800mA output current with a maximum input voltage of 5.5V and a low dropout voltage of 0.4V at 800mA. It features an enable pin for enhanced control and offers robust protection against over current, over temperature, short circuit, and under voltage lockout (UVLO). The device exhibits a typical quiescent current of 30 µA and a supply current of 8 mA (max). With a wide operating temperature range of -40°C to 125°C, the LP3891ET-1-5-NOPB is suitable for applications in automotive, industrial, and consumer electronics. Its high power supply rejection ratio (PSRR) of 80dB to 65dB across a frequency range of 120Hz to 1kHz ensures stable performance in noisy environments. The regulator is supplied in a TO-220-5 package with formed leads, designed for through-hole mounting.
