NCP171AMX330310TCG

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

The NCP171AMX330310TCG is a dual-output low-dropout (LDO) linear voltage regulator manufactured by onsemi. It features two independent positive fixed output channels, each capable of delivering up to 80mA. The device operates with an input voltage range from 1.7V to 5.5V and provides a fixed 3.3V output. Key electrical parameters include a maximum dropout voltage of 55mV at 80mA load and a quiescent current of 95µA. The regulator incorporates overcurrent protection and thermal shutdown for safety. It is housed in a compact 4-pin XDFN package measuring 1.2mm x 1.2mm with a height of 0.4mm, suitable for surface-mount applications operating between -40°C and +85°C.

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

Verify the specific suffix codes against official datasheets to confirm output configurations and packaging variants. Ensure compatibility with existing PCB footprints and thermal management requirements. Confirm availability through authorized distributors as supply chain conditions may vary. Check for RoHS compliance status relevant to your region's regulatory standards before finalizing procurement decisions.

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

Select this component when dual isolated outputs are required in a minimal footprint application. Consider the 80mA per channel limit for load requirements. Evaluate the 1.7V minimum input voltage against your source supply to ensure adequate headroom. Compare quiescent current specifications against battery life requirements for portable designs.

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

This part belongs to the NCP171 series of wide input voltage LDO regulators from onsemi. The series is designed for applications demanding high PSRR and low noise in small packages. The NCP171AMX330310TCG specifically denotes the dual-output variant with 3.3V fixed outputs, distinguishing it from single-output or adjustable versions within the same family.

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

Check for direct pin-compatible alternatives within the NCP171 family that offer different output voltages or current ratings. Verify if newer revisions of the component have updated packaging or material specifications. Cross-reference with other dual-output LDOs from various manufacturers only if electrical parameters and package dimensions match exactly.
