XC6501D28AMR-G

Part Overview

The XC6501D28AMR-G is a linear voltage regulator IC manufactured by Torex Semiconductor Ltd, classified as a Power Management (PMIC) component. This device is a positive fixed 1-output regulator rated for 200mA output current with a fixed output voltage of 2.85V, housed in an SOT-25 package. The part is currently in active production status with 981 units available in stock as new original inventory. Alternative models become necessary when addressing specific design requirements such as higher output current capacity, improved thermal performance, enhanced protection features, or different packaging configurations while maintaining functional equivalency in the 2.8–2.85V output range.

Substitute Part Grouping Explanation

Two substitute parts are identified for the XC6501D28AMR-G based on electrical and mechanical parameter compatibility within the linear voltage regulator category:

S-1315A2J-M5T1U3 (ABLIC Inc.) – Classified as a parametric equivalent. This part maintains the identical fixed output voltage of 2.85V and identical output current rating of 200mA, matching the core electrical specifications of the main part. The key differentiator is the superior quiescent current performance (1 µA versus 20 µA) and lower dropout voltage (0.28V @ 200mA versus 0.36V @ 200mA). Both parts operate within the -40°C to 85°C temperature range and feature enable control with over current protection. Package compatibility exists in the SC-74A/SOT-753 family, though the supplier device package differs (SOT-23-5 versus SOT-25).

TLV70228PDBVT (Texas Instruments) – Classified as a similar manufacturer part. This regulator shares the same output voltage class (2.8V, within 0.05V of the 2.85V specification) and functional category but operates at a higher output current capacity of 300mA, making it suitable for applications requiring greater current delivery. The input voltage limit is lower (5.5V versus 6V), and protection features are expanded to include over temperature, reverse polarity, and UVLO protection in addition to over current protection. Operating temperature extends to 125°C (TJ) versus 85°C for the main part. Both parts conform to the same regulatory standards and share package family classification.

Parameter Comparison

Engineering Selection Recommendations

All three components—XC6501D28AMR-G, S-1315A2J-M5T1U3, and TLV70228PDBVT—are active products with ROHS3 compliance and unlimited moisture sensitivity levels, indicating they are suitable for production use with no functional obsolescence risk.

The S-1315A2J-M5T1U3 serves as the direct parametric equivalent when pin-to-pin compatibility is achievable within the SOT-25/SOT-23-5 package family. It offers superior performance characteristics including lower quiescent current and improved dropout voltage, making it the preferred choice when design margins permit the supplier device package transition from SOT-25 to SOT-23-5.

The TLV70228PDBVT is selected when application requirements demand higher output current (300mA versus 200mA), extended operating temperature range to 125°C, or enhanced protection features including reverse polarity and under-voltage lockout. The input voltage maximum of 5.5V versus 6V for the main part must be verified against actual system input conditions. Higher quiescent current (55 µA versus 20 µA) impacts battery-powered or ultra-low-power applications and should be evaluated against the performance benefits of additional protection features.

Frequently Asked Questions (FAQ)

Q: Can S-1315A2J-M5T1U3 be used as a direct drop-in replacement for XC6501D28AMR-G?

A: Both parts maintain the same fixed output voltage (2.85V) and output current rating (200mA), with compatible package families (SC-74A/SOT-753). However, the supplier device package differs—the main part uses SOT-25 while the substitute uses SOT-23-5. Pin compatibility within the SC-74A family must be confirmed with layout and schematic review. The superior performance of the S-1315A2J-M5T1U3 (lower dropout voltage and quiescent current) presents no functional risk in direct substitution.

Q: What are the key differences between the two substitute parts?

A: S-1315A2J-M5T1U3 provides electrical parameter parity with improved performance metrics (lower Iq and dropout voltage), operating within identical voltage and current ranges. TLV70228PDBVT increases output current capacity to 300mA, extends operating temperature range to 125°C, and adds reverse polarity and UVLO protection features. The choice depends on whether higher current capacity and extended protection are necessary for the application.

Q: What happens to input voltage limits when substituting to TLV70228PDBVT?

A: The main part accepts 6V maximum input, while TLV70228PDBVT limits input to 5.5V. If the application supplies 5.5V to 6V at the regulator input, TLV70228PDBVT cannot be used without upstream voltage limiting. The input voltage specification of the system must be reviewed before selecting this alternative.

Q: How does quiescent current affect selection?

A: The main part draws 20 µA quiescent current, S-1315A2J-M5T1U3 draws 1 µA, and TLV70228PDBVT draws 55 µA. In always-on applications with substantial load current, this difference is negligible. In battery-powered or standby applications with light loads, the lower quiescent current of S-1315A2J-M5T1U3 extends battery life, while the higher quiescent current of TLV70228PDBVT may accelerate battery discharge. Load profile analysis determines the practical impact of this parameter.

Q: Are package transitions between SOT-25 and SOT-23-5 compatible?

A: Both packages belong to the SC-74A/SOT-753 family and are commonly used interchangeably in similar applications. However, physical board layout, printed circuit board footprints, and pinout assignments must be verified in the component datasheets. A package transition requires design review before deployment.

Q: What regulatory and compliance standards apply to all parts?

A: All three components are ROHS3 compliant, classified as REACH Unaffected, and assigned ECCN EAR99 with HTSUS 8542.39.0001. They carry MSL 1 (unlimited moisture sensitivity), eliminating shelf-life moisture exposure concerns. All parts maintain active production status, ensuring continued availability and supply chain stability.
