Procurement Notes
Verify the specific suffix 'SNG' corresponds to the SOT-25 package and tape-and-reel quantity when ordering. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer prior to procurement. Ensure the application circuit supports the required input-to-output differential for optimal regulation performance.
Selection Notes
Select this component when a fixed 2.8V rail is required with moderate current demands up to 150mA. It is appropriate for systems where low static current consumption is critical during standby modes. Consider the SOT-25 footprint constraints and ensure adequate thermal dissipation for the expected ambient operating conditions.
Part Context
This part belongs to the AP7311 series of low dropout regulators from Diodes Incorporated. The series offers various fixed output voltages and packages, designed for efficiency in portable applications. The AP7311 variant specifically targets single-channel regulation needs with integrated protection features.
Replacement Considerations
Compatible substitutes include other 2.8V LDOs in SOT-25 packages from manufacturers such as Microchip or Texas Instruments, provided pinouts and electrical specifications match. Verify equivalent dropout voltage and quiescent current requirements before substitution.
