RT9013-33GB

RT9013-33GB is a Richtek fixed 3.3 V low-dropout linear regulator in a SOT-23-5 package, rated at 500 mA output from a 2.2 V to 5.5 V input, with 250 mV dropout and 25 µA quiescent current — a battery-friendly 3.3 V rail for portable and embedded designs, in the GB SOT-23-5 ordering form. Lifecycle, stated without softening: Richtek's own product page lists this part's status as EOL. That makes this page a sustaining-production and spares channel, not a new-design recommendation — if you are designing in a 3.3 V, 500 mA-class LDO today, ask us to point you at a current-production Richtek equivalent instead; if your released product is qualified on the RT9013-33GB, this is the exact code to keep buying, and lot and date-code requirements matter more than usual on an end-of-life part, so state them explicitly in the RFQ. Selection advice: the low 25 µA quiescent current is why designs chose it for battery rails; any replacement candidate for a redesign should be checked on Iq and dropout together, not on output voltage alone. Parameters verified against Richtek documentation.
