Texas Instruments LP3881ES-1-8 is an 800mA positive fixed voltage linear regulator with an output voltage of 1.8V. This device features an enable pin for control and offers excellent Power Supply Rejection Ratio (PSRR) of 80dB to 65dB across a frequency range of 120Hz to 1kHz, making it suitable for noise-sensitive applications. The quiescent current is a low 30µA. Protection features include over current, over temperature, short circuit, and under voltage lockout (UVLO). With a maximum input voltage of 5.5V and a dropout voltage of 0.16V at 800mA, it is designed for surface mount applications in the TO-263 (DDPAK-5) package. This regulator is commonly employed in telecommunications, industrial, and automotive systems.
