Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific ordering suffix 'M5T1U3' corresponds to the SOT-23-5 package and tape reel packing format as defined in the official datasheet. Confirm that the 'C' type designation matches the requirement for unavailable discharge shunt and available pull-down resistor functions. Ensure environmental compliance codes align with lead-free and halogen-free specifications before finalizing procurement orders.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed 2.0 V output is required with low quiescent current consumption. The C-type configuration is suitable for applications where the discharge shunt function is not needed but a pull-down resistor on the ON/OFF pin is desired for stability. Ensure external ceramic capacitors of 0.22 μF or more are used for both input and output stabilization to prevent oscillation.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the S-1312 Series of 5.5 V input, 150 mA voltage regulators developed by ABLIC Inc. using CMOS technology. The series offers selectable output voltages from 1.0 V to 3.5 V in 0.05 V steps. The S-1312C variant specifically denotes a product type with active high ON/OFF logic, no discharge shunt function, and an available pull-down resistor.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct substitutes within the same series include other S-1312C variants with different output voltages (e.g., S-1312C18-M5T1U3 for 1.8 V) if the voltage requirement changes. Cross-series replacements require verification of pin compatibility and electrical characteristics against the S-1312 datasheet specifications.
