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

Verify the specific ordering suffix against the manufacturer's datasheet to confirm package type (SNT-6A(H)) and environmental compliance (Lead-free, Sn 100%, halogen-free). Confirm that the pin configuration matches the S-1112 series requirements, as it differs from the S-1122 series. Ensure the selected component meets the required operating temperature range and power dissipation constraints for the target application.

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

Select this component when a fixed 3.0 V output is required with high accuracy and low quiescent current. Consider the SNT-6A(H) package for its compact footprint suitable for high-density mounting. Evaluate the thermal performance based on the maximum power dissipation ratings provided in the datasheet, especially under high load conditions or elevated ambient temperatures.

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

This part belongs to the S-1112/1122 Series of CMOS voltage regulators developed by ABLIC Inc. The series is characterized by high ripple rejection and low dropout voltage. The S-1112 variant specifically utilizes the SNT-6A(H) or SOT-23-5 packages, distinguishing itself from the S-1122 series through its pin configuration and internal logic levels for the ON/OFF pin.
