TC2015-2.8VCTTR Equivalent & Substitute Parts

Part Overview

The TC2015-2.8VCTTR is a linear voltage regulator IC from Microchip Technology designed for positive fixed 2.8V output applications. This Surface Mount device operates in the SOT-23-5 package and delivers 100mA output current with a maximum dropout voltage of 0.14V at rated load. The part is Active status and ROHS3 compliant, suitable for low-power supply regulation in portable and embedded systems.

Substitute Part Grouping Explanation

Substitution logic for the TC2015-2.8VCTTR is based on the following allowed parameters:

Fixed Output Voltage: All substitutes maintain 2.8V output to ensure direct compatibility with downstream circuitry.

Output Current Capability: Substitutes are grouped by current rating. Parts with 100mA output (TC1015-2.8VCT713, TC2055-2.8VCTTR) provide direct replacement capability. Parts with 150mA (MIC5255-2.8YD5-TR, MIC5255-2.8YM5-TR) or 300mA (MIC5323-2.8YD5-TR) offer increased headroom for higher-load applications.

Input Voltage Range: All substitutes accept maximum input voltage of 5.5V to 6V, compatible with the original specification.

Dropout Voltage: Substitutes range from 0.14V to 0.25V at their respective rated currents. Lower dropout voltage (0.14V) is preferred for battery-powered applications.

Package Type: SOT-23-5 and TSOT-23-5 packages are mechanically and electrically compatible for Surface Mount assembly.

Operating Temperature: All substitutes maintain -40°C to 125°C range, ensuring thermal compatibility.

Protection Features: All substitutes include Over Current and Over Temperature protection as minimum requirements.

Engineering Selection Recommendations

All listed substitute parts are Active status products from Microchip Technology and maintain ROHS3 compliance and REACH unaffected status, consistent with the original TC2015-2.8VCTTR specification.

Direct Replacement (100mA Output): TC2055-2.8VCTTR and TC1015-2.8VCT713 provide parametric equivalence with identical 100mA output current. TC2055-2.8VCTTR matches the original dropout voltage specification of 0.14V, while TC1015-2.8VCT713 exhibits 0.25V dropout voltage.

Increased Current Capacity (150mA Output): MIC5255-2.8YM5-TR (SOT-23-5) and MIC5255-2.8YD5-TR (TSOT-23-5) provide 50% additional output current while maintaining 6V maximum input voltage. Both include Under Voltage Lockout (UVLO) protection in addition to Over Current and Over Temperature features.

High Current Applications (300mA Output): MIC5323-2.8YD5-TR delivers 300mA output current in TSOT-23-5 package with improved PSRR performance (80dB to 65dB across 1kHz to 10kHz). Maximum input voltage is 5.5V, requiring design verification for applications exceeding this specification.

Frequently Asked Questions (FAQ)

Q: Can TC2055-2.8VCTTR directly replace TC2015-2.8VCTTR?

A: Yes. Both parts deliver 100mA output current at 2.8V fixed output with 0.14V dropout voltage at rated load, identical quiescent current of 80 µA, and SOT-23-5 package compatibility. Operating temperature range and protection features are equivalent.

Q: What is the difference between MIC5255-2.8YM5-TR and MIC5255-2.8YD5-TR?

A: Both deliver 150mA output current at 2.8V with identical electrical performance. MIC5255-2.8YM5-TR uses SOT-23-5 package (SC-74A, SOT-753), while MIC5255-2.8YD5-TR uses TSOT-23-5 (thin variant). Package selection depends on PCB layout and assembly process requirements.

Q: When should MIC5323-2.8YD5-TR be selected over MIC5255 variants?

A: MIC5323-2.8YD5-TR is selected when output current demand exceeds 150mA and reaches 300mA. The part offers superior PSRR performance (80dB to 65dB) compared to MIC5255 (60dB to 50dB). Maximum input voltage is limited to 5.5V; applications requiring 6V input must use MIC5255 or TC-series alternatives.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. All listed substitute parts are supplied in Tape & Reel (TR) packaging for automated assembly processes, consistent with the original TC2015-2.8VCTTR specification.

Q: What protection features distinguish MIC5255 from TC2015?

A: MIC5255 series includes Under Voltage Lockout (UVLO) protection in addition to Over Current and Over Temperature protection. TC2015 and TC1015 include Over Current and Over Temperature protection only. UVLO prevents regulator operation when input voltage falls below a defined threshold.

Q: Is PCB layout compatibility maintained across all substitute parts?

A: SOT-23-5 and TSOT-23-5 packages share identical pin configuration and footprint compatibility. TSOT-23-5 is a thinner variant suitable for space-constrained applications. Verify PCB assembly equipment specifications for thin package handling capability.
