LP3964EMP-3.3/NOPB TI LDO Regulator | SOT-223-5 | 3.3V Output, 800mA

Product Overview

The LP3964EMP-3.3/NOPB is a high-performance, low-dropout (LDO) voltage regulator from Texas Instruments (TI). It delivers a fixed output voltage of 3.3V with a maximum output current of 800mA. Housed in a compact SOT-223-5 package, this device is designed for space-constrained applications requiring low noise and high power supply rejection ratio (PSRR). The LP3964 features a low dropout voltage of typically 240mV at full load, making it suitable for battery-powered systems. Its enable pin allows for power sequencing and shutdown control, reducing quiescent current to near zero when disabled. The device includes overcurrent and overtemperature protection, ensuring reliable operation under fault conditions.
