R1163N311B-TR-FE

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

The R1163N311B-TR-FE is a low-dropout (LDO) voltage regulator manufactured by Nisshinbo Micro Devices. It provides a fixed output voltage of 3.1 V with a maximum load current capability of 150 mA. The device features manual ECO mode shift functionality and incorporates reverse current protection to prevent backflow when the input voltage drops below the output level. It operates within an input voltage range up to 6 V and maintains performance across a temperature range of -40°C to +85°C. The component is housed in a compact SOT-23-5 surface-mount package, suitable for space-constrained portable electronics.

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

Verify the exact suffix against the manufacturer's latest datasheet to confirm pinout compatibility and specific electrical tolerances. Ensure the ordering code matches the required output voltage and package type. Cross-reference with official distributor catalogs to validate RoHS compliance status and availability for the target region before finalizing procurement plans.

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

Select this component when a fixed 3.1 V supply is required with minimal quiescent current draw. The reverse current protection feature makes it suitable for systems where input power may be removed while the output capacitor remains charged. Consider the SOT-23-5 footprint constraints and thermal dissipation requirements relative to the expected load current and ambient temperature conditions.

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

This part belongs to the R1163N series of LDO regulators from Nisshinbo Micro Devices. The series is characterized by its ultra-low standby current and manual ECO mode operation, designed primarily for battery-operated applications. The '311' designation indicates the specific 3.1 V output voltage variant, while 'B' typically denotes the package and tape/reel configuration details defined by the manufacturer.

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

Direct replacements must match the 3.1 V output, 150 mA current rating, SOT-23-5 package, and reverse current protection feature. Verify pin-to-pin compatibility and thermal characteristics before substitution.
