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

Verify the specific suffix PR-G corresponds to the SOT-89 package and 1000-piece reel quantity. Confirm the 'N' designation indicates the 85°C operating temperature range rather than the 105°C variant. Ensure compliance with EU RoHS and lead-free requirements as indicated by the '-G' suffix before finalizing procurement specifications.

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

Select this component when a stable negative voltage rail is required for portable electronics. The fixed -4.0V output eliminates external resistor networks. Consider the SOT-89 package for higher power dissipation capabilities compared to smaller packages. Verify that the input voltage remains within the -2.4V to -16V range for proper regulation.

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

This part belongs to the XC6902 series of three-terminal negative voltage regulators. The series offers various fixed output voltages ranging from -0.9V to -12V. The 'N' type specifies a maximum operating temperature of 85°C, while the 'P' type supports up to 105°C. All variants share similar internal architectures including error amplifiers and phase compensators.

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

Check for other XC6902 variants with different output voltages or temperature ratings if system requirements change. The XC6902N401MR-G offers the same electrical characteristics but in an SOT-23-3 package.
