Needs validationhigh risk
GR6220B331MR-G is a lower-current 3.3V LDO candidate in SOT-23-5.
Best Alternatives to ME6217C33M5G
ME6217C33M5G is a 3.3V, 800mA fixed LDO in SOT-23-5. Current rating and pinout are the main barriers to substitution.
AI replacement insight
Electrical riskhigh
kept parts are 300/500mA vs 800mA
Package riskmedium
package matches but pinout is missing
Firmware risklow
no digital interface shown
Sourcing riskmedium
lifecycle data is limited
Can it be replaced directly?
No verified pin-compatible replacement is proven from the provided data.
Best replacement path
Use 3.3V fixed SOT-23-5 LDOs only after pinout and load-current review.
Main risk
Most candidates are far below the 800mA target current.
