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

Verify the specific suffix 'T1' against the manufacturer's official datasheet to confirm reel packaging specifications and tape-and-reel dimensions. Ensure the part number matches the exact output voltage tolerance and package variant required for your design. Cross-reference with the latest Nisshinbo Micro Devices documentation to avoid obsolete revisions.

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

Select this component when a stable 4.1V supply is needed with high current demand under low headroom conditions. The adjustable version of the R1173x series allows for prototyping before finalizing the fixed voltage standard version. Consider the SOT-89-5 package size constraints and thermal dissipation requirements for the target application environment.

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

This part belongs to the R1173x series of low-voltage LDO regulators designed for applications requiring large currents with minimal voltage drop. The series includes both internally set output voltage versions and adjustable versions for flexible design implementation. These regulators are halogen-free and RoHS compliant.

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

The R1172H411D-T1-FE is a comparable fixed-output alternative within the same family, though it lacks the adjust pin found in the R1173x series. Verify pinout compatibility and thermal performance differences before substitution.
