RP152L057A-TR

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

The RP152L057A-TR is a dual-channel low dropout (LDO) voltage regulator manufactured by Nisshinbo Micro Devices Inc. It provides two fixed output voltages of 3.1V and 1.8V, each capable of delivering up to 150mA. The device operates with a maximum input voltage of 5.25V and features integrated overcurrent protection. Packaged in a compact 6-pin DFN1212-6 format, it is designed for applications requiring precise power sequencing and stable regulation in space-constrained environments.

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

Verify the specific suffix 'A' against the official datasheet to confirm the exact output voltage combination of 3.1V and 1.8V. Ensure the DFN1212-6 package footprint matches the design layout. Confirm RoHS compliance status through the manufacturer's documentation before finalizing procurement specifications.

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

Select this component when dual isolated outputs are required within a minimal footprint. The 150mA per channel rating suits low-to-moderate current loads. Verify that the input voltage range up to 5.25V aligns with the system supply. The built-in sequence control eliminates external timing components, simplifying the schematic design.

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

This part belongs to the RP152x series of low voltage dual-channel LDO regulators. The series is characterized by high ripple rejection and low dropout performance. The RP152L057A-TR specifically denotes the fixed output variant with sequence control capabilities, distinguishing it from adjustable or single-channel counterparts in the same family.

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

Check for other RP152L variants with different output voltages if the 3.1V/1.8V combination is not suitable. Ensure any substitute maintains the DFN1212-6 package and 150mA current rating. Verify that the replacement also supports the required sequence control feature.
