The -40°C to 125°C operating temperature range covers under-hood and cabin environments without derating. The 2 MHz switching frequency keeps the power stage outside the AM band and lets you use small, low-profile inductors — a real advantage when board area is tight. ## Lifecycle and sourcing posture The LP873344RHDTQ1 is listed as Active with ROHS3 compliance. For dual-sourcing flexibility, the LP873244RHDTQ1 (2 A buck version) is a drop-in alternative that shares the same package, pinout, and sequencer — useful for second-source qualification or cost optimisation on lower-current builds.","metaTitle":"LP873344RHDTQ1 Automotive PMIC","metaDescription":"LP873344RHDTQ1 is an AEC-Q100 qualified PMIC with dual 3 A step-down converters and dual 300 mA LDOs.
