Parameter Comparison

Engineering Selection Recommendations

Both the XC6221B26AMR-G and XC6217B26AMR-G are active production components from Torex Semiconductor Ltd with identical RoHS3 compliance and REACH unaffected status. The parts are mechanically and electrically interchangeable within the specified SOT-25 package footprint and operating temperature range of -40°C ~ 85°C.

The XC6217B26AMR-G demonstrates superior quiescent current performance at 8 µA compared to the XC6221B26AMR-G at 50 µA, resulting in lower standby power consumption. This characteristic makes the XC6217B26AMR-G advantageous for battery-powered or low-power standby applications where quiescent current is a design constraint.

Both parts maintain identical output voltage (2.65V), output current (200mA), dropout voltage (0.17V @ 100mA), PSRR (70dB @ 1kHz), and control/protection features. Selection between these parts depends on application-specific quiescent current requirements and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the XC6217B26AMR-G directly replace the XC6221B26AMR-G in existing designs?
