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

Verify the specific suffix 'T1G' against official onsemi documentation to confirm tape-and-reel packaging and RoHS compliance status. Ensure the ordering part number matches the exact output voltage variant required for the design. Cross-reference the manufacturer's latest datasheet revision to confirm pinout compatibility and any potential obsolescence notices prior to procurement.

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

Select this component when a stable 2.8 V rail is required for low-power digital loads. The 120 mA output capability supports moderate current demands while maintaining low quiescent current characteristics. Verify that the input voltage remains above the minimum threshold of 1.7 V under all operating conditions to ensure proper regulation and prevent dropout issues.

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

This device belongs to the NCP580 family of low-noise LDO regulators designed for portable applications. The family offers various fixed output voltages in a small footprint. The NCP580 series emphasizes low static current and high power supply rejection ratio (PSRR) to minimize noise in sensitive analog and RF sections of battery-operated systems.

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

Check onsemi documentation for direct pin-compatible alternatives within the NCP580 series offering different output voltages or current ratings. Verify electrical parameter equivalence before substituting with other manufacturers' LDOs.
