CAT811STBI-GT3

onsemi

The CAT811STBI-GT3 is an onsemi microprocessor supervisory circuit in SOT-143 that watches the supply rail and holds the controller in reset until the voltage is safely in range, protecting embedded systems from brown-out corruption in a four-lead footprint. Selection advice: this is the corrected factory code — the '-MS' seen on some channel listings is a distributor marking, not part of the onsemi orderable number. Lifecycle honesty: onsemi lists the CAT811STBI-GT3 as Obsolete, so this page serves legacy maintenance and last-time-buy demand; send an RFQ with quantity and date-code requirements and we will confirm available original stock. Parameters verified against onsemi documentation.
