Parameter Comparison

Engineering Selection Recommendations

MIC5365-1.5YMT-TZ (Microchip Technology) This part is electrically and mechanically identical to the MIC5366-1.5YMT-TZ with identical package, voltage, current, and protection specifications. It is actively produced with significantly higher inventory availability (45,300 pieces). Selection is appropriate when supply of the MIC5366 is constrained.

LD39020DTPU15R (STMicroelectronics) This part meets all critical electrical parameters with 200mA output current capability, exceeding the 150mA requirement. The dropout voltage is lower (0.35V @ 200mA). Package differs (4-DFN vs. 4-TMLF®), requiring PCB layout verification. Soft start protection is included. Selection is appropriate for applications requiring higher current margin or lower dropout performance, provided package compatibility is confirmed.

NCV8170AMX150TCG (onsemi) This part meets all critical electrical parameters with identical 150mA output current. Quiescent current is significantly lower (0.9 µA vs. 39 µA), beneficial for battery-powered applications. Package differs (4-XDFN vs. 4-TMLF®), requiring PCB layout verification. Automotive grade with AEC-Q100 qualification. Selection is appropriate for automotive applications or designs prioritizing low quiescent current, provided package compatibility is confirmed.

NCV8170BMX150TCG (onsemi) This part meets all critical electrical parameters with identical 150mA output current. Quiescent current is significantly lower (0.9 µA vs. 39 µA). Package differs (4-XDFN vs. 4-TMLF®), requiring PCB layout verification. Automotive grade with AEC-Q100 qualification.

Frequently Asked Questions (FAQ)

Q: Can MIC5365-1.5YMT-TZ be used as a direct replacement for MIC5366-1.5YMT-TZ? A: Yes. Both parts are from Microchip Technology with identical electrical specifications, output voltage (1.5V), output current (150mA), package type (4-TMLF®), and operating temperature range (-40°C to 125°C). No design changes are required.

Q: What is the key difference between LD39020DTPU15R and MIC5366-1.5YMT-TZ? A: The LD39020DTPU15R provides higher output current (200mA vs. 150mA), lower dropout voltage (0.35V vs. 0.38V), and includes soft start protection. The package differs (4-DFN vs. 4-TMLF®), requiring PCB footprint verification before substitution.

Q: Why do NCV8170AMX150TCG and NCV8170BMX150TCG have much lower quiescent current? A: The NCV8170 series is designed with ultra-low quiescent current (0.9 µA) compared to the MIC5366 (39 µA). This is a design characteristic of the onsemi part family, beneficial for battery-powered or low-power standby applications.

Q: Are the onsemi NCV8170 parts suitable for automotive applications? A: Yes. Both NCV8170AMX150TCG and NCV8170BMX150TCG carry automotive grade designation with AEC-Q100 qualification. The MIC5366-1.5YMT-TZ does not specify automotive qualification.

Q: Do all substitute parts use the same package as the MIC5366-1.5YMT-TZ? A: No. MIC5365-1.5YMT-TZ uses the same 4-TMLF® package. LD39020DTPU15R uses 4-DFN, and both NCV8170 variants use 4-XDFN. Package differences require PCB layout verification and may not be pin-compatible without design modification.

Q: What compliance certifications apply to all listed parts? A: All parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8542.39.0001. All have moisture sensitivity level (MSL) of 1 (unlimited).
