R1114D201A-TR-FE

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The R1114D201A-TR-FE is a fixed-output low-dropout (LDO) voltage regulator manufactured by Nisshinbo Micro Devices. It belongs to the R1114D series and provides a stable 2.0 V output with a maximum continuous current of 150 mA. The device utilizes a SON1612-6 surface-mount package designed for compact circuit board layouts. It operates within an input voltage range of 2 V to 6 V and maintains performance across a temperature range of -40°C to +85°C. Key electrical characteristics include a typical power supply rejection ratio (PSRR) of 60 dB and a dropout voltage of 280 mV.

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

Verify the specific output voltage code within the part number to ensure it matches the required 2.0 V specification. Confirm that the SON1612-6 package footprint aligns with the target PCB design. Check RoHS compliance documentation for environmental regulatory requirements. Ensure the operating temperature range meets the application's thermal constraints. Validate that the 150 mA current rating is sufficient for the peak load demands of the circuit.

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

Select this component when a fixed 2.0 V rail is needed with moderate current capacity. The SON1612-6 package offers a small form factor compared to larger regulators. Consider the 60 dB PSRR if the input source contains significant switching noise. The wide input voltage range allows flexibility in battery-powered designs where voltage drops over time. Ensure the thermal dissipation capabilities of the PCB support the expected power loss at full load.

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

This regulator is part of the R1114D family, which includes various fixed output voltages and packages. The 'D' suffix indicates the SON1612-6 package type, distinguishing it from other series variants like R1114N or R1114Q. These devices are CMOS-based LDOs designed for low quiescent current operation. The series is commonly used in consumer electronics and industrial applications requiring reliable voltage regulation in space-constrained environments.

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

Direct substitutes may include other R1114D series parts with different output voltages if the voltage requirement changes. Cross-reference with R1114N or R1114Q series parts only if package compatibility can be addressed through adapter solutions. Verify pinout compatibility before replacing with non-series equivalents. Ensure any replacement maintains the same current rating and thermal performance characteristics.
