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

Verify the complete part number including suffixes to confirm specific packaging and tape-and-reel specifications. Confirm that the required output voltage matches the fixed 1.8 V variant, as other voltages exist in the same series. Ensure compatibility with the target PCB footprint for the XDFN-4 package before finalizing procurement orders.

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

Select this component when a fixed 1.8 V rail is required with minimal static current draw. It is suitable for designs where input voltage remains above 2.2 V. Consider alternative packages if higher current capacity or adjustable output is needed, as this model is optimized for low-power, fixed-voltage automotive applications.

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

This device belongs to the NCV8170 family of ultra-low IQ LDO regulators manufactured by onsemi. The family includes various fixed output voltages and packages, all sharing similar low-power characteristics. The NCV8170AMX180TCG specifically denotes the 1.8 V output version in the XDFN-4 surface-mount package, tailored for space-constrained automotive electronics.

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

NCV8170BMX180TCG offers identical electrical performance in a different package configuration. NCV8170AXV180T2G provides the same voltage regulation in a SOT-563 package. Verify pinout compatibility and thermal requirements when substituting these alternatives.
