LP3964EMP-1.8/NOPB TI LDO Regulator | SOT-223-5 | 1.8V Fixed Output, 800mA

Product Overview

The LP3964EMP-1.8/NOPB is a high-performance low-dropout (LDO) voltage regulator from Texas Instruments, designed to deliver a fixed 1.8V output with a maximum current of 800mA. Housed in a compact SOT-223-5 package, this device offers excellent line and load regulation, making it ideal for noise-sensitive applications. The LP3964 features a low dropout voltage of typically 240mV at full load, enabling efficient operation even with minimal input-to-output voltage differential. Its enable pin allows for power sequencing and shutdown control, reducing quiescent current to near zero when disabled. With built-in overcurrent and thermal shutdown protection, the LP3964 ensures reliable performance in demanding environments.
