SOT-223 Voltage Regulator / Power IC – Top Mark VS 58 – Bench-Indicated 3.3V
$0.99
SOT-223 style voltage regulator / power IC sold from RF Boneyard bench stock.
This device has a top marking of VS / 58 and uses a SOT-223 style package with three lower leads and a large upper heat tab. Component analyzer testing indicated voltage regulator mode, and one bench reading suggested possible 3.3V regulator behavior with an indicated output near 3.288V.
Because the exact manufacturer, full part number, pinout, and final output regulation have not been confirmed, this part is listed as bench-identified / ID-pending repair stock. It may be useful for technicians working with SOT-223 regulator circuits, 3.3V power rails, radio control boards, logic boards, display boards, and general electronics repair where the buyer can verify the exact device and circuit requirements.
Buyer must verify top marking, datasheet match, pinout, input/output/ground pins, output voltage, enable/control behavior if present, and circuit compatibility before installation.
