A functional alternative with higher 300mA current, 18V input, and better dropout in the same package.
XC6202P332MR is a common 3.3V, 150mA LDO voltage regulator in a SOT-23-3 package. Several functional alternatives are available, often with upgraded current or voltage ratings, but require careful verification of pinout and key electrical parameters like dropout voltage before substitution.
Variations in dropout voltage and quiescent current require review for specific applications.
All viable candidates use the same SOT-23-3 package, but pinout must be confirmed.
Multiple manufacturers offer suitable alternatives, indicating good supply chain depth.
No direct drop-in replacement is confirmed without datasheet pinout verification. RS7533-1YF3 matches key specs but requires review of its dropout voltage.
Upgrade to higher current parts like SSP7603P33MR or ME6214A33M3G after verifying pinout from datasheets.
Pinout incompatibility is the main risk, which could cause circuit failure if not verified before assembly.
