Procurement Notes
Verify the specific ordering suffix to confirm the package type and tape & reel quantity. Confirm compliance requirements such as RoHS status and halogen-free specifications before procurement. Check datasheet revision history for any updates to electrical characteristics or recommended operating conditions.
Selection Notes
Select this component for designs requiring a fixed 1.5V rail with moderate current demands up to 150mA. Ensure the input voltage remains within the 2.5V to 5.5V range. Consider the SOT-25 package size and thermal resistance when designing the PCB layout for adequate heat dissipation under load.
Part Context
This part belongs to the AP7115 series of low dropout linear regulators from Diodes Incorporated. It is designed for portable electronics where low quiescent current and small form factor are critical. The series offers various fixed output voltages and packaging options to suit different design constraints.
Replacement Considerations
The datasheet explicitly states that the AP7115 is not recommended for new designs and recommends using the AP7315 instead. Verify if the AP7315 meets all electrical and physical requirements for the application.
