R1163N331E-TR-FE

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

The R1163N331E-TR-FE is a fixed-output low-dropout (LDO) linear voltage regulator manufactured by Nisshinbo Micro Devices Inc. It provides a stable 3.3 V output with a maximum current capacity of 150 mA. The device operates within an input voltage range up to 6 V and features a typical power supply rejection ratio (PSRR) of 70 dB at 1 kHz, dropping to 60 dB at 10 kHz. It includes built-in overcurrent protection and reverse current protection functions. The component is designed for surface-mount installation in a compact 6-SMD, flat lead package, specifically identified as 6-SON (2.6x1.6).

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

Verify the specific suffix 'E' against official Nisshinbo documentation to confirm pinout and electrical characteristics, as distributor listings may not explicitly detail suffix variations. Ensure the ordering code matches the exact package type required for your PCB design. Cross-reference the manufacturer part number with authorized distributors to confirm availability and authenticity before finalizing procurement plans.

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

Select this component when a fixed 3.3 V output is required with moderate current demands up to 150 mA. The 6-V maximum input voltage limits its use to lower-voltage systems. Consider the 6-SON package size for board space constraints. Evaluate the PSRR requirements against the 70 dB specification to ensure adequate noise rejection for sensitive analog sections of the design.

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

This part belongs to the R1163x series of LDO regulators from Nisshinbo Micro Devices. The series is characterized by low quiescent current and integrated protection features. The R1163N331E variant specifically denotes the 3.3 V fixed output version within this family, sharing common architectural traits with other outputs in the series while differing in internal reference voltage settings.

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

Direct substitutes include other parts from the R1163x series with different output voltages if system architecture allows adjustment. Verify compatibility regarding package dimensions and pin configurations when considering alternative manufacturers or series upgrades.
