LP3878SD-1.0/NOPB TI Low-Dropout Regulator | 8-WSON (4x4) | 1.0V Fixed Output, 800mA

Product Overview

The LP3878SD-1.0/NOPB is a low-dropout (LDO) voltage regulator from Texas Instruments, designed to deliver a fixed 1.0V output with a maximum current of 800mA. Housed in an 8-pin WSON package (4x4 mm), this device offers excellent line and load regulation, making it suitable for noise-sensitive applications. The LP3878 features a low dropout voltage of typically 240mV at full load, enabling efficient operation even with low input-to-output voltage differentials. Its enable pin allows for power sequencing and shutdown control, reducing quiescent current to near zero when disabled.
