How it works

Step 1 / 3

Identify the shipment

Check the CSO identifier: SFB legacy, RFB/FFAB new. Do not infer silicon solely from the output voltage.

Step 2 / 3

Bypass for that revision

The new-chip example uses 1 µF effective ceramic COUT, within the specified ESR range. Legacy guidance is different.

Step 3 / 3

Cool the output tab

The tab is OUT. Its PCB copper removes heat but must not short to ground.
