RP131L501D-TR

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

The RP131L501D-TR is a discontinued low voltage LDO regulator from the RP131x series, manufactured by Nisshinbo Micro Devices Inc. It provides a fixed 5V output with a maximum current capability of 1A. The device operates within an input voltage range of 1.6V to 6.5V and utilizes a DFN1616-6B package. Key electrical characteristics include a typical supply current of 65µA, standby current of 0.15µA, and ripple rejection of 70dB at 1kHz. It features built-in protections including over-current, short-circuit, and thermal shutdown.

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

Verify component status before procurement as the RP131L series was officially discontinued in April 2023. Confirm availability through authorized distributors or secondary markets. Ensure compatibility with existing PCB footprints and design specifications given the discontinuation. Review datasheet revisions for any final manufacturing changes prior to integration into new designs.

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

Select this component only if the specific DFN1616-6B package and 5V fixed output are required. Consider alternative packages like DFN(PL)1820-6 (RP131K series) if higher density mounting is needed. Evaluate the auto discharge feature necessity for system power-down requirements. Verify input voltage ranges and load conditions against the absolute maximum ratings to ensure reliable operation.

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

The RP131L501D-TR belongs to the RP131x series of low voltage LDO regulators designed for high-density mounting applications. This series offers various package options including SOT-89-5, HSOP-6J, and TO-252-5-P2. The 'L' suffix denotes the DFN1616-6B package, while 'D' indicates the inclusion of an auto discharge function. The '501' specifies the fixed 5.0V output voltage setting.

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

Consider the RP131K501D-TR as a direct substitute using the DFN(PL)1820-6 package. Other family members like RP131H, RP131S, or RP131J offer different package types but maintain similar electrical performance. Verify pinout compatibility and thermal dissipation characteristics when transitioning between package variants.
