Engineering Selection Recommendations

The R1180Q301B-TR-FE serves as a direct parametric equivalent to the R1114Q301A-TR-FE for applications requiring a 3V, 150mA linear voltage regulator in SC-82A / SOT-343 surface mount packaging. Both devices maintain identical output voltage, output current, input voltage maximum, operating temperature range, control features, and protection features.

Selection Basis:

The R1180Q301B-TR-FE demonstrates superior quiescent current performance (1.5 µA versus 95 µA), resulting in lower standby power consumption. The maximum voltage dropout specification of 0.4V at 150mA is marginally higher than the R1114Q301A-TR-FE (0.35V), remaining within acceptable tolerance for most 3V regulated supply applications.

Both parts maintain active product status and comply with RoHS regulations. The R1180Q301B-TR-FE carries ROHS3 compliance certification, representing the current regulatory standard. Both devices are classified under EAR99 export control and HTSUS code 8542.39.0001.

Selection between these parts should be based on application-specific requirements for quiescent current performance and dropout voltage tolerance, with both parts providing equivalent functional capability in the specified package configuration.

Frequently Asked Questions (FAQ)

Q: Can the R1180Q301B-TR-FE replace the R1114Q301A-TR-FE in existing designs?
