TPS22918DBVR

TPS22918DBVR is a Texas Instruments single-channel load switch in a SOT-23-6 package, for 1 V to 5.5 V rails at up to 2 A with a 52 mΩ typical on-resistance at 5 V — lower conduction loss than the TPS22917 at the same current. Quiescent current is 8.3 µA typical at 3.3 V and shutdown current 0.5 µA typical; the rise time is configurable for inrush limiting and the quick-output-discharge level is adjustable, over −40 to +105 °C. Selection advice: this part has no reverse-current blocking — if the output can be driven above the input (battery changeover, supply OR-ing, a charged output bulk capacitor), the TPS22917 is the correct sibling; the two parts' on-resistance and quiescent figures also differ, so do not swap them on a qualified BOM without re-checking the power budget. The DBVR code is SOT-23-6 tape and reel. TI lists this code as Active (Production). Parameters verified against Texas Instruments documentation.
