Texas Instruments LP3891ESX-1-2 is an ultra-low-noise, high-speed LDO linear voltage regulator. This positive fixed output device offers an 800mA output current with a low dropout voltage of 0.4V at 800mA. Featuring an output voltage of 1.2V, the LP3891ESX-1-2 operates from an input voltage range up to 5.5V. Key control features include an Enable pin for power sequencing. Protection mechanisms are integrated, comprising over current, over temperature, short circuit, and under voltage lockout (UVLO). The device exhibits excellent power supply rejection ratio (PSRR) performance, ranging from 80dB down to 65dB across frequencies from 120Hz to 1kHz. With a quiescent current of 30µA, it is suitable for power-sensitive applications. The LP3891ESX-1-2 is supplied in a TO-263-6, D2PAK package, suitable for surface mounting. Industries benefiting from this component include telecommunications, automotive, and industrial control systems. It is supplied in Tape & Reel (TR) packaging.
