The Texas Instruments LP3891ESX-1.2 is a high-current, fast-response linear voltage regulator designed for applications requiring stable voltage regulation with minimal input-to-output voltage drop. This device operates with an input voltage range of 1.3V to 5.5V and delivers a fixed 1.2V output at up to 0.8A.
Key electrical specifications include an ultra-low dropout voltage of 100mV at 0.8A typical, a typical quiescent current of 4mA, and an accuracy of 2% at 25°C. Protection features such as over-current, over-temperature, and short-circuit protection are integrated for enhanced reliability. The regulator also includes an enable control feature.
Packaged in a DDPAK/TO-263-5 surface-mount package, the LP3891ESX-1.2 is suitable for various electronic designs. It operates within a wide temperature range of -40°C to 125°C, making it robust for demanding environments. The device is RoHS3 compliant.
