Parameter Comparison

Engineering Selection Recommendations

R1180N151B-TR-FE (Nisshinbo Micro Devices Inc.)

This substitute maintains identical electrical specifications with the primary exception of increased voltage dropout (0.9V versus 0.7V). The R1180N151B-TR-FE demonstrates significantly reduced quiescent current (1.5µA versus 95µA), resulting in improved power efficiency during standby operation. Both devices share identical package geometry (SOT-23-5), control architecture, and protection mechanisms. The part maintains active product status with RoHS compliance and unlimited moisture sensitivity rating. Selection of this substitute is appropriate when quiescent current reduction is a design priority and the additional 0.2V dropout margin is acceptable within the application circuit.

XC6504A151MR-G (Torex Semiconductor Ltd)

This substitute delivers equivalent output voltage and current specifications with identical operating temperature range and enable/over-current protection features. The XC6504A151MR-G exhibits the lowest quiescent current (1.27µA) among all options, supporting maximum power efficiency. The device carries ROHS3 compliance certification and unlimited moisture sensitivity rating. The primary design consideration is the elevated voltage dropout specification (1.63V @ 150mA), which requires verification that the application circuit maintains adequate input voltage margin. Package designation differs slightly (SOT-25-5 versus SOT-23-5), though both utilize SC-74A case geometry suitable for surface-mount assembly.

Frequently Asked Questions (FAQ)

Q: Can R1180N151B-TR-FE directly replace R1114N151A-TR-FE in existing PCB layouts?

A: Yes. Both devices utilize identical SOT-23-5 package geometry (SC-74A case) with matching pin configurations. Direct PCB substitution is supported without layout modification. The increased voltage dropout (0.9V versus 0.7V) requires verification that input voltage remains sufficient for proper regulation.

Q: What is the primary difference between R1114N151A-TR-FE and R1180N151B-TR-FE?

A: The R1180N151B-TR-FE reduces quiescent current from 95µA to 1.5µA, improving standby power consumption. Voltage dropout increases from 0.7V to 0.9V. Both devices maintain identical output voltage (1.5V), output current (150mA), and operating temperature range (-40°C to 85°C).

Q: Is XC6504A151MR-G compatible with R1114N151A-TR-FE applications?

A: Functional compatibility exists for applications where the elevated voltage dropout (1.63V @ 150mA) does not compromise circuit operation. The device delivers identical output voltage and current specifications with superior quiescent current performance (1.27µA). PCB layout compatibility requires verification due to SOT-25-5 package designation, though both utilize SC-74A case geometry.

Q: What does the voltage dropout specification mean for circuit design?

A: Voltage dropout represents the minimum voltage differential required between input and output terminals for proper regulation at maximum output current (150mA). The R1114N151A-TR-FE requires 0.7V minimum differential, while R1180N151B-TR-FE requires 0.9V and XC6504A151MR-G requires 1.63V. Applications must ensure input voltage exceeds output voltage plus the applicable dropout specification.

Q: Are all three parts RoHS compliant?

A: Yes. R1114N151A-TR-FE and R1180N151B-TR-FE carry RoHS compliance certification. XC6504A151MR-G carries ROHS3 compliance certification. All three devices maintain unlimited moisture sensitivity rating (MSL 1).

Q: Which substitute offers the best power efficiency?

A: XC6504A151MR-G demonstrates the lowest quiescent current (1.27µA), followed by R1180N151B-TR-FE (1.5µA). The original R1114N151A-TR-FE operates at 95µA quiescent current. Lower quiescent current reduces standby power consumption in battery-powered or always-on applications.

Q: Can these parts be used interchangeably in high-noise environments?

A: R1114N151A-TR-FE specifies PSRR performance (70dB ~ 60dB at 1kHz ~ 10kHz), providing documented noise rejection characteristics. R1180N151B-TR-FE and XC6504A151MR-G do not specify PSRR values. Applications requiring documented power supply rejection ratio performance should prioritize R1114N151A-TR-FE.
