1-A, 3.3 V fixed low-IQ LDO with enable and active discharge, 2 x 2 mm WSON-6
The Texas Instruments TLV75733P is the 3.3 V fixed-output member of the TLV757P family of 1-A, low-quiescent-current, high-accuracy low-dropout regulators. It accepts 1.45 V to 5.5 V input, draws only 25 µA quiescent current and adds foldback current limit, soft start, active output discharge, thermal shutdown and UVLO. It is widely used for point-of-load regulation in set-top boxes, routers, IP cameras, industrial sensors and consumer electronics. Current lead time is around 26 weeks with authorized stock constrained; Cerametronics helps buyers source traceable stock.

Quality & Traceability
Cerametronics is ISO 9001 certified and products are RoHS compliant, with counterfeit screening and full traceability on every shipment. A Certificate of Conformance is available on request. For allocation-sensitive or high-risk lots, independent third-party lab verification can be arranged — just flag it on your RFQ. Any lot that fails incoming inspection is quarantined and never shipped.
FAQ
Is there a TLV75733PDRVT small-reel version?
TI's package option addendum lists only TLV75733PDRVR and TLV75733PDRVRG4, both on 3,000-piece large tape-and-reel; no 250-piece T-suffix orderable is listed for the 3.3 V DRV option. The G4 suffix is the same part with a different green-packaging code and is a direct substitute.
What alternatives exist if the WSON-6 version cannot be sourced?
The same 3.3 V output is available in SOT-23-5 (TLV75733PDBVR) and the thermally enhanced SOT-23-5 with pad (TLV75733PDYDR), but these have a different footprint. TI names the newer TLV777 as a pin-for-pin compatible alternative with higher PSRR, and the TLV759P as an adjustable, cost-oriented option with a different pinout.
