AP7315Q-28W5-7 Equivalent & Substitute Parts

Part Overview

The AP7315Q-28W5-7 is a linear voltage regulator IC from Diodes Incorporated, classified as a Power Management (PMIC) component. This device delivers a fixed positive output of 2.8V at 150mA with a maximum dropout voltage of 0.29V, housed in an SOT-25 package. The part is actively produced, automotive-grade (AEC-Q100 qualified), and ROHS3 compliant. Substitute parts are identified when electrical specifications, output configuration, package type, and compliance certifications remain identical across alternative manufacturer part numbers from the same supplier.
