LP873220RHDRQ1 TI Power Management IC | 28-VQFN (5x5) | Dual Buck, LDO

Product Overview

The LP873220RHDRQ1 is a high-performance power management IC (PMIC) from Texas Instruments, designed for automotive and industrial applications. It integrates two step-down DC/DC converters and one low-dropout (LDO) regulator in a compact 28-pin VQFN (5x5 mm) package. The device operates over a wide input voltage range of 2.5V to 5.5V, making it suitable for battery-powered and point-of-load applications. With its high efficiency, low quiescent current, and robust protection features, the LP873220RHDRQ1 is ideal for powering processors, FPGAs, and other sensitive loads in automotive infotainment, ADAS, and industrial control systems.
