Parameter Comparison

Engineering Selection Recommendations

XC6701B302ER-G is the primary component selection when quiescent current performance and power supply rejection ratio are critical design parameters. This part delivers 50dB PSRR at 1kHz and 105µA quiescent current, suitable for applications requiring superior noise rejection and moderate standby power consumption.

XC6216B302ER-G is the substitute selection when ultra-low quiescent current is the primary design objective. This part reduces quiescent current to 9µA while maintaining identical output voltage, output current, dropout voltage, and operating temperature specifications. The PSRR specification is reduced to 30dB at 1kHz, which remains suitable for applications with less stringent noise rejection requirements.

Both parts are manufactured by Torex Semiconductor Ltd, carry active product status, maintain ROHS3 compliance, and feature identical MSL ratings. Both are available in the same 6-UFDFN Exposed Pad package with Surface Mount configuration, ensuring mechanical and thermal compatibility in PCB layouts.

Selection between these parts depends on whether the application prioritizes noise rejection performance (XC6701B302ER-G) or standby power efficiency (XC6216B302ER-G). Both are qualified for the full -40°C to 85°C operating temperature range and include identical over-current and over-temperature protection features.

Frequently Asked Questions (FAQ)

Q: Can XC6216B302ER-G replace XC6701B302ER-G in existing designs?

A: Yes, the XC6216B302ER-G is a parametric equivalent substitute. Both parts deliver identical output voltage (3V), output current (150mA), input voltage rating (28V maximum), dropout voltage (1.7V @ 100mA), and operating temperature range (-40°C to 85°C). The primary difference is quiescent current (9µA versus 105µA) and PSRR (30dB versus 50dB). Substitution is valid when these performance differences are acceptable to the application requirements.

Q: What are the key differences between XC6701B302ER-G and XC6216B302ER-G?

A: The XC6216B302ER-G features significantly lower quiescent current at 9µA compared to 105µA in the XC6701B302ER-G. The XC6701B302ER-G provides superior power supply rejection ratio at 50dB (1kHz) versus 30dB (1kHz) in the XC6216B302ER-G. All other electrical and mechanical specifications are identical.

Q: Are both parts available in the same package?

A: Yes. Both XC6701B302ER-G and XC6216B302ER-G use the 6-UFDFN Exposed Pad package with 6-USPC (1.8x2) dimensions. Both are Surface Mount components with identical pinout and PCB footprint compatibility.

Q: Which part should I select for low-power battery applications?

A: The XC6216B302ER-G is the appropriate selection for battery-powered applications due to its 9µA quiescent current specification, which minimizes standby power drain compared to the 105µA quiescent current of the XC6701B302ER-G.

Q: Which part should I select for noise-sensitive applications?

A: The XC6701B302ER-G is the appropriate selection for applications requiring superior noise rejection, as it provides 50dB PSRR at 1kHz compared to 30dB PSRR in the XC6216B302ER-G.

Q: Are both parts RoHS compliant?

A: Yes. Both XC6701B302ER-G and XC6216B302ER-G are ROHS3 compliant and carry MSL rating of 1 (Unlimited moisture sensitivity level).

Q: Do both parts include the same protection features?

A: Yes. Both parts include Over Current and Over Temperature protection features and feature Enable control functionality.

Q: What is the maximum input voltage for both parts?

A: Both XC6701B302ER-G and XC6216B302ER-G accept input voltages up to 28V maximum.

Q: What is the dropout voltage specification for both parts?

A: Both parts specify a maximum dropout voltage of 1.7V at 100mA output current.
