LP3997MM-3.3/NOPB TI LDO Regulator | 8-VSSOP | 3.3V Output, 150mA

Product Overview

The LP3997MM-3.3/NOPB is a low-dropout (LDO) linear voltage regulator from Texas Instruments, designed to deliver a fixed 3.3V output with a maximum output current of 150mA. Housed in an 8-VSSOP package, this device offers excellent line and load regulation, making it suitable for noise-sensitive applications. The LP3997 features a low dropout voltage of typically 120mV at 150mA load, enabling efficient operation even with small input-to-output voltage differentials. Its low quiescent current (typically 30µA) helps extend battery life in portable devices. The device includes overcurrent and overtemperature protection, ensuring reliable operation under fault conditions.
