Procurement Notes
Verify the specific ordering suffix FS4-7B to confirm the X2-DFN1010-4 package and tape-and-reel packaging quantity. Ensure the component matches the non-discharge variant indicated by the absence of 'D' in the part number. Confirm RoHS compliance and lead-free status through official manufacturer documentation before finalizing procurement specifications.
Selection Notes
Select this component when a stable 1.2V rail is required for sensitive RF or portable applications. The wide input voltage range supports lithium-ion battery operation. Verify that the PCB layout accommodates the X2-DFN1010-4 footprint and thermal pad requirements. Ensure the load current does not exceed the guaranteed 150mA limit under all operating conditions.
Part Context
This part belongs to the AP7315 series of low dropout regulators designed for low power handheld communication equipment. The series offers various fixed output voltages and packages. The AP7315-12FS4-7B specifically targets applications requiring high accuracy and low noise in a compact form factor.
Replacement Considerations
Consult the official datasheet for alternative package options such as SOT23 or SOT25 if footprint changes are permissible. Verify electrical compatibility for any cross-brand replacements.
