XC6217B28AMR-G Linear Voltage Regulator Equivalent & Substitute Parts

Part Overview

The XC6217B28AMR-G is an active linear voltage regulator IC manufactured by Torex Semiconductor Ltd, classified as a Power Management (PMIC) component. This device delivers a fixed positive output of 2.85V at 200mA with a maximum dropout voltage of 0.17V at 100mA. The regulator features enable control and over-current protection, operating across the industrial temperature range of -40°C to 85°C. Currently in active production status with 614 units in stock, this component is packaged in SOT-25 (SC-74A, SOT-753) surface mount configuration and is ROHS3 compliant with unlimited moisture sensitivity rating.

Equivalent and substitute parts are identified to address supply chain continuity, inventory optimization, and design flexibility while maintaining functional and electrical compatibility within the specified parameter envelope.

Substitute Part Grouping Explanation

Substitute parts for the XC6217B28AMR-G are identified based on strict electrical and mechanical parameter alignment. The substitution criteria are:

Primary Matching Parameters:

• Fixed output voltage of 2.85V
• Output current rating of 200mA
• Positive output configuration with single regulator
• Enable control feature and over-current protection
• Operating temperature range of -40°C to 85°C
• ROHS3 compliance and unlimited MSL rating
• Surface mount packaging (SOT-23-5 or SOT-25 compatible footprints)

Secondary Compatibility Factors:

• Input voltage maximum rating (6V for main part; 5.5V for substitute)
• Dropout voltage performance (0.17V @ 100mA for main part; 0.28V @ 200mA for substitute)
• Quiescent current specifications (8µA for main part; 1µA for substitute)
• PSRR performance (70dB for main part; 55dB for substitute)

The S-1315A2J-M5T1U3 meets all primary matching parameters and maintains functional equivalence for 2.85V fixed output regulation at 200mA across the specified temperature range. Differences in secondary parameters reflect manufacturer design variations and do not preclude substitution in applications where the specified performance envelope is acceptable.

Parameter Comparison

Engineering Selection Recommendations

XC6217B28AMR-G Selection Criteria:

• Primary choice for applications requiring maximum input voltage tolerance up to 6V
• Preferred for designs prioritizing lower dropout voltage performance (0.17V @ 100mA)
• Suitable for noise-sensitive applications requiring higher PSRR (70dB @ 1kHz)
• Available in Tape & Reel packaging format for high-volume production environments
• Active product status with established supply chain and 614 units in current inventory

S-1315A2J-M5T1U3 Selection Criteria:

• Suitable for applications with input voltage maximum of 5.5V or lower
• Advantageous for battery-powered or low-power designs due to lower quiescent current (1µA vs. 8µA)
• Acceptable for applications where PSRR of 55dB @ 1kHz meets performance requirements
• Available in Cut Tape packaging format for lower-volume or prototype applications
• Active product status with 861 units in current inventory

Both parts maintain ROHS3 compliance, unlimited MSL rating, and identical operating temperature range (-40°C to 85°C). Selection between these components depends on specific application requirements regarding input voltage range, dropout voltage performance, quiescent current consumption, and noise rejection specifications.

Frequently Asked Questions (FAQ)

Q: Can the S-1315A2J-M5T1U3 be used as a direct replacement for the XC6217B28AMR-G in all applications?

A: The S-1315A2J-M5T1U3 is functionally equivalent for fixed 2.85V output regulation at 200mA across -40°C to 85°C. However, applications requiring input voltages above 5.5V must use the XC6217B28AMR-G, which supports up to 6V input. Additionally, designs sensitive to dropout voltage performance should verify that the S-1315A2J-M5T1U3 dropout specification (0.28V @ 200mA) is acceptable versus the XC6217B28AMR-G specification (0.17V @ 100mA).

Q: What are the package compatibility considerations between SOT-25 and SOT-23-5?

A: Both the XC6217B28AMR-G (SOT-25) and S-1315A2J-M5T1U3 (SOT-23-5) use the SC-74A footprint designation. Physical pin configurations and PCB layout compatibility must be verified against manufacturer datasheets before substitution. While both are 5-pin surface mount packages, dimensional differences may exist that affect board-level integration.

Q: How do the quiescent current differences impact circuit design?

A: The S-1315A2J-M5T1U3 exhibits significantly lower quiescent current (1µA) compared to the XC6217B28AMR-G (8µA). This 7µA difference is negligible in most applications but becomes relevant in ultra-low-power or battery-powered designs where standby current consumption is critical. The XC6217B28AMR-G may be preferred in applications where quiescent current is not a limiting factor.

Q: Are there compliance or certification differences between these parts?

A: Both parts are ROHS3 compliant, carry unlimited MSL rating (Level 1), and are classified as REACH Unaffected with EAR99 export classification. No compliance or certification differences exist between the XC6217B28AMR-G and S-1315A2J-M5T1U3.

Q: What is the significance of the PSRR difference (70dB vs. 55dB)?

A: PSRR (Power Supply Rejection Ratio) measures the regulator's ability to reject input voltage ripple and noise. The XC6217B28AMR-G provides superior noise rejection at 70dB @ 1kHz compared to the S-1315A2J-M5T1U3 at 55dB @ 1kHz. Applications requiring low-noise output or operating in high-noise environments should prioritize the XC6217B28AMR-G.

Q: What packaging format differences exist between Tape & Reel and Cut Tape?

A: The XC6217B28AMR-G is supplied in Tape & Reel (TR) format, suitable for automated pick-and-place assembly in high-volume production. The S-1315A2J-M5T1U3 is supplied in Cut Tape (CT) format, typically used for lower-volume applications, prototyping, or manual assembly. Format selection depends on production volume and assembly methodology rather than electrical performance.
