A strong functional alternative with matched voltage/current and much lower quiescent current. Pinout and dropout must be reviewed.
TCR2EF33,LM(CT is a 3.3V, 200mA LDO from Toshiba in a SOT-25 package. Finding a replacement involves matching key electricals and verifying the SOT-23-5/SOT-25 package pinout.
SOT-23-5 and SOT-25 often share footprints but pinouts must be verified.
Candidates may have higher minimum input voltage or dropout voltage.
Multiple alternatives exist from major manufacturers.
No confirmed pin-to-pin replacement has been identified. The most promising candidate, TPS7A0333DBVR, requires datasheet review to confirm its SOT-23-5 pinout matches the target's SOT-25 footprint.
TPS7A0333DBVR is the strongest functional alternative, offering matched core specs and much lower quiescent current. However, pinout and dropout voltage must be verified before use.
The primary risks are package/pinout incompatibility and differences in electrical parameters like minimum input voltage and dropout voltage.
