R1116N151D-TR-FE

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

The R1116N151D-TR-FE is a low-dropout (LDO) voltage regulator manufactured by Nisshinbo Micro Devices. It belongs to the R1116D series and provides a fixed output voltage of 2.9 V with a maximum output current of 150 mA. The device utilizes a 6-pin SON package (SON1612-6) designed for surface-mount technology. It operates within an input voltage range up to 6 V and supports a junction temperature range from -40°C to +85°C. Key electrical characteristics include a typical power supply rejection ratio (PSRR) of 53 dB and a dropout voltage of 290 mV at full load.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Seamless transition between operating modes without output voltage interruption or oscillation during mode shifts.
• Integrated reverse current protection circuit prevents backflow from the output to the input when the input voltage drops below the output voltage.
• Fixed output voltage configuration ensures stable regulation without requiring external feedback resistors.

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

• Portable electronic devices requiring efficient power management from single-cell lithium batteries.
• Battery-powered sensors and modules needing stable low-voltage supply rails.
• Embedded systems utilizing CMOS logic circuits sensitive to power supply noise.

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

Verify the specific suffix 'D' indicates the SON1612-6 package variant, distinct from the 'N' series SOT-23-5 packaging. Confirm the '151' code corresponds to the 2.9 V fixed output setting. Ensure compatibility with the required thermal dissipation capabilities for the target application environment. Cross-reference the manufacturer's latest datasheet for any updates on pin configurations or absolute maximum ratings before finalizing the design.

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

Select this component when a compact footprint is prioritized over the SOT-23-5 form factor. The 150 mA output current capability suits moderate load applications. Consider the 290 mV dropout voltage relative to the minimum available input voltage headroom. The integrated reverse current protection is advantageous in systems where input power may be disconnected while the output remains charged by capacitive loads.

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

This part is a member of the R1116D series, which distinguishes itself through the use of the small SON1612-6 package. Unlike the R1116N series which uses SOT-23-5, the D-series offers a different physical profile suitable for space-constrained PCB layouts. The series shares core features such as seamless mode switching and reverse current protection across its variants.

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

The R1116N151B-TR-FE serves as a functional alternative within the same series but utilizes an SOT-23-5 package instead of the SON1612-6 form factor. Designers must account for the physical footprint differences when substituting. Other R1116D variants with different output voltages require verification of the voltage setting code.
