LP3972SQ-0514/NOPB TI Power Management IC | PMIC | 2.7V-5.5V, 4 Regulators

Product Overview

The LP3972SQ-0514/NOPB is a high-performance power management IC (PMIC) from Texas Instruments, designed for portable and battery-powered applications. It integrates four low-dropout regulators (LDOs), a buck-boost converter, and a battery charger, providing a compact and efficient power solution. The device operates from a single Li-Ion cell or 2.7V to 5.5V input, delivering regulated outputs with low quiescent current. Its small package and high integration make it ideal for space-constrained designs.
