Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AP7315D-285FS4-7B are identified based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

• Fixed output voltage of 2.85V
• Output current capability of 150mA
• Maximum input voltage of 5.25V
• Maximum dropout voltage of 0.29V @ 150mA
• 4-XDFN Exposed Pad package configuration
• Surface Mount mounting type
• Operating temperature range of -40°C to 85°C
• Active product status
• RoHS3 compliance

Parts meeting all these parameters are classified as direct parametric equivalents and may be used interchangeably in circuit designs without modification to the PCB layout or schematic topology.
