Engineering Selection Recommendations

All three parts—S-T111B30MC-OGPTFU, S-1112B30MC-L6PTFU, and S-1167A30-M5T1U—are Active product status devices manufactured by ABLIC Inc. and are ROHS3 compliant with REACH unaffected status. They are suitable for direct substitution in applications requiring a 3V, 150mA linear regulator in SOT-23-5 packaging.

The S-1112B30MC-L6PTFU maintains identical electrical specifications to the S-T111B30MC-OGPTFU, including dropout voltage and quiescent current characteristics.

The S-1167A30-M5T1U offers improved performance characteristics with lower dropout voltage (0.23V versus 0.26V at 100mA), reduced quiescent current (900nA versus 1µA), and significantly lower supply current (16µA versus 90µA). These improvements may provide benefits in power-sensitive applications, though PSRR is reduced to 70dB compared to 80dB in the primary part.

Frequently Asked Questions (FAQ)

Q: Can S-1112B30MC-L6PTFU be used as a direct replacement for S-T111B30MC-OGPTFU?

A: Yes. The S-1112B30MC-L6PTFU is a parametric equivalent with identical electrical specifications including output voltage (3V), output current (150mA), input voltage maximum (6.5V), dropout voltage (0.26V @ 100mA), and package type (SOT-23-5). Both devices are Active status and ROHS3 compliant.

Q: What are the differences between S-1167A30-M5T1U and S-T111B30MC-OGPTFU?

A: The S-1167A30-M5T1U maintains the same output voltage (3V), output current (150mA), input voltage maximum (6.5V), and package type (SOT-23-5). Differences include lower dropout voltage (0.23V versus 0.26V at 100mA), lower quiescent current (900nA versus 1µA), lower supply current (16µA versus 90µA), and lower PSRR (70dB versus 80dB at 1kHz).

Q: Are all substitute parts available in the same packaging?

A: Yes. All three parts use SOT-23-5 packaging (SC-74A, SOT-753) with Surface Mount mounting type, ensuring mechanical compatibility in PCB layouts.

Q: Do all parts meet the same compliance requirements?

A: Yes. S-T111B30MC-OGPTFU, S-1112B30MC-L6PTFU, and S-1167A30-M5T1U are all ROHS3 compliant, REACH unaffected, and classified as Active product status.

Q: Which substitute part should be selected for power-sensitive applications?

A: Selection depends on specific application requirements. The S-1167A30-M5T1U offers lower quiescent current (900nA) and supply current (16µA) compared to the primary part (1µA and 90µA respectively), making it suitable for battery-powered or low-power applications. The S-1112B30MC-L6PTFU maintains identical specifications to the primary part for applications requiring consistent performance characteristics.
