Engineering Selection Recommendations

Both the XC6501D26AMR-G and XC6217B26AMR-G are active products manufactured by Torex Semiconductor Ltd with full RoHS3 compliance and REACH unaffected status. Selection between these devices is based on application-specific requirements within the specified parameter envelope.

The XC6501D26AMR-G is suitable for applications where the specified dropout voltage of 0.38V at 200mA and quiescent current of 20µA meet design requirements.

The XC6217B26AMR-G provides improved performance with reduced dropout voltage of 0.17V at 100mA and lower quiescent current of 8µA, making it advantageous for power-sensitive or low-headroom applications. Both devices maintain identical output voltage, current capacity, input voltage rating, package configuration, and regulatory compliance.

Component selection should be based on availability, lead time, and specific application performance requirements within the defined electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Are the XC6501D26AMR-G and XC6217B26AMR-G pin-compatible?

A: Yes. Both devices use the SOT-25 (SC-74A, SOT-753) package configuration with identical pin assignments for surface-mount applications.

Q: Can the XC6217B26AMR-G replace the XC6501D26AMR-G in existing designs?

A: Yes. The XC6217B26AMR-G meets all electrical and mechanical equivalence criteria. The device provides identical output voltage (2.65V), output current (200mA), input voltage rating (6V maximum), and control/protection features. The improved dropout voltage and lower quiescent current represent performance enhancements with no parameter degradation.

Q: What is the difference in dropout voltage between these devices?

A: The XC6501D26AMR-G specifies 0.38V dropout at 200mA. The XC6217B26AMR-G specifies 0.17V dropout at 100mA. The XC6217B26AMR-G demonstrates lower dropout performance, beneficial in applications with limited input-to-output voltage margin.

Q: Do both devices support the same control features?

A: Yes. Both the XC6501D26AMR-G and XC6217B26AMR-G include enable control functionality and over-current protection.

Q: Are there any regulatory compliance differences?

A: No. Both devices are RoHS3 compliant, REACH unaffected, and maintain active product status with identical regulatory classification.

Q: What is the quiescent current difference?

A: The XC6501D26AMR-G draws 20µA quiescent current. The XC6217B26AMR-G draws 8µA quiescent current. The lower quiescent current of the XC6217B26AMR-G reduces standby power consumption in battery-powered or always-on applications.

Q: Can these devices operate across the same temperature range?

A: Yes. Both devices operate from -40°C to 85°C (TA), supporting industrial temperature applications.

Q: What is the PSRR difference and its significance?

A: The XC6501D26AMR-G provides 50dB PSRR at 1kHz. The XC6217B26AMR-G provides 70dB PSRR at 1kHz. Higher PSRR indicates superior rejection of input voltage ripple and noise, beneficial in applications with noisy power sources.
