Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, meeting regulatory requirements equivalent to the TC2015-2.5VCTTR.

MIC5255-2.5YD5-TR and MIC5255-2.5YM5-TR provide 150mA output current capacity with enhanced PSRR performance and integrated Under Voltage Lockout protection. These are suitable for applications requiring higher current delivery or improved noise rejection. Package selection between TSOT-23-5 (MIC5255-2.5YD5-TR) and SOT-23-5 (MIC5255-2.5YM5-TR) depends on PCB layout requirements.

MIC5259-2.5YD5-TR delivers 300mA output current with superior PSRR characteristics, appropriate for higher-power applications within the 2.5V fixed output specification. The increased dropout voltage (0.55V @ 300mA) must be evaluated against circuit headroom requirements.

TC1015-2.5VCT713 is a parametric equivalent maintaining 100mA output current and identical quiescent current specification. This part offers improved dropout voltage performance (0.25V @ 100mA) and enhanced PSRR (64dB at 1kHz) while preserving the original current rating.

Frequently Asked Questions (FAQ)

Q: Can MIC5255-2.5YD5-TR replace TC2015-2.5VCTTR directly?

A: Yes, with consideration for increased output current capability (150mA vs 100mA) and enhanced protection features. The higher quiescent current (150 µA vs 80 µA) and increased dropout voltage (0.25V vs 0.14V) must be evaluated for specific circuit requirements. TSOT-23-5 package dimensions differ slightly from SOT-23-5; verify PCB footprint compatibility.

Q: What is the difference between MIC5255-2.5YD5-TR and MIC5255-2.5YM5-TR?

A: Both parts are electrically identical with 150mA output current and identical electrical specifications. The primary difference is packaging: MIC5255-2.5YD5-TR uses TSOT-23-5 (thin profile), while MIC5255-2.5YM5-TR uses standard SOT-23-5. Select based on PCB assembly requirements and available footprint space.

Q: When should MIC5259-2.5YD5-TR be selected over other substitutes?

A: MIC5259-2.5YD5-TR is appropriate for applications requiring 300mA output current within the 2.5V fixed output specification. The significantly higher dropout voltage (0.55V @ 300mA) requires adequate input-to-output voltage margin. This part is not suitable for applications limited to 100mA current draw.

Q: Is TC1015-2.5VCT713 a direct replacement for TC2015-2.5VCTTR?

A: TC1015-2.5VCT713 is a parametric equivalent maintaining identical output current (100mA) and quiescent current (80 µA). It offers improved dropout voltage and PSRR performance. Both parts use SOT-23-5 packaging and are fully compatible from electrical and mechanical perspectives.

Q: Do all substitute parts include Under Voltage Lockout protection?

A: No. TC2015-2.5VCTTR and TC1015-2.5VCT713 include Over Current and Over Temperature protection only. MIC5255 and MIC5259 series parts include additional Under Voltage Lockout (UVLO) protection. Verify circuit requirements for UVLO functionality before selection.

Q: Are all parts ROHS3 compliant?

A: Yes. TC2015-2.5VCTTR, MIC5255-2.5YD5-TR, MIC5255-2.5YM5-TR, MIC5259-2.5YD5-TR, and TC1015-2.5VCT713 are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).
