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

Verify the manufacturer designation, as this part number is associated with onsemi rather than Fairchild Semiconductor. Confirm the specific suffix indicates the 2.8 V fixed output variant. Ensure the WLCSP package type matches the target PCB layout requirements. Cross-reference official datasheets to validate the 250 mA current rating and 2.8 V output specification before finalizing procurement orders.

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

Select this component when a compact form factor is required alongside moderate current delivery. The WLCSP package offers significant space savings compared to traditional leaded packages. The 2.8 V output is suitable for powering digital logic or RF front-ends requiring that specific rail. Consider the 250 mA limit for total system load calculations to ensure adequate headroom during peak operation.
