Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify that the component matches the specific X2-DFN1010-4 package type designated by the FS4 suffix. Confirm the fixed output voltage is exactly 2.85V as indicated by the model code. Ensure the ordering suffix corresponds to tape and reel packaging quantities. Cross-reference the manufacturer part number against official datasheets to validate authenticity before integration into designs.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this regulator when a compact footprint is required alongside high PSRR specifications. The device is suitable for battery-powered applications due to its low quiescent current profile. Designers must ensure the input voltage remains within the specified operating range while accounting for dropout voltage variations across temperature extremes. Verify compatibility with required ceramic output capacitor values for stability.
