Procurement Notes
Verify the specific ordering suffix FS4-7B corresponds to the X2-DFN1010-4 package and tape & reel packaging configuration. Confirm that the non-discharge variant matches system requirements, as discharge versions carry a different suffix. Ensure compliance with RoHS and halogen-free standards during procurement.
Selection Notes
Select this component when a precise 1.1V rail is required for sensitive RF or logic circuits. The low noise profile supports audio and video subsystems. Verify input voltage stability remains above 1.7V. Consider thermal dissipation limits in dense PCB layouts due to the small footprint.
Part Context
This part belongs to the AP7315 series of CMOS LDO regulators designed for handheld communication equipment. It offers high PSRR and low dropout characteristics suitable for battery-powered devices. The series includes various fixed output voltages and packages to support diverse portable electronics applications.

FAQ
What is the function of the EN pin?
The EN pin enables or disables the regulator. Driving it high turns the regulator on, while pulling it low puts it into shutdown mode.
Does this part include an auto-discharge feature?
No, the AP7315-11FS4-7B does not have an auto-discharge feature. The 'D' suffix indicates the presence of an internal discharge resistor.
