Texas Instruments
200 mA ultra-low-IQ LDO, 3.3 V fixed output, 1 µA IQ, 1 x 1 mm X2SON
The Texas Instruments TPS7A0533PDQNR is a 3.3 V, 200 mA low-dropout regulator with 1 µA typical quiescent current, built for battery-powered wearables, IoT nodes and always-on rails. Authorized stock is at zero and lead times are quoted around 26 weeks, which is stalling builds that standardized on the 1 x 1 mm X2SON package. Cerametronics helps buyers locate traceable stock to keep production moving.

Any lot that fails incoming inspection is quarantined and never shipped.
FAQ
Are other packages of TPS7A0533 available?
Yes, TI offers the same 3.3 V device in SOT-23 (DBV) and other packages, but the footprint differs from the 1 x 1 mm X2SON (DQN), so it is not a drop-in replacement.
What is the difference between TPS7A0533PDQNR and TPS7A0533PDQNT?
They are the same device; the R and T suffixes indicate different reel quantities.
