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

Verify the exact suffix designation against official datasheets to confirm pinout and electrical specifications. Confirm availability status as distribution channels may list obsolete or end-of-life inventory. Ensure compliance with RoHS directives if required for your specific manufacturing environment. Cross-reference manufacturer part numbers to avoid substitution errors during procurement.

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

Select this component when an adjustable output voltage is required alongside high current capacity. Consider the SOT-223-3 package for surface-mount assembly constraints. Evaluate thermal dissipation requirements given the 1 A output capability and dropout voltage characteristics. Ensure the input voltage range aligns with your system's power source limitations.

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

This device belongs to the FAN1117 series of low-dropout regulators from onsemi. The series includes various fixed and adjustable voltage variants packaged in different form factors such as TO-220 and TO-252. The ASX suffix specifically denotes the adjustable version in the SOT-223-3 package, distinguishing it from fixed-voltage counterparts within the same family.

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

Check for direct cross-references from other manufacturers offering identical pinouts and electrical parameters. Verify that any substitute component matches the 1 A current rating and 17 V maximum input voltage. Ensure thermal performance characteristics are comparable to maintain system reliability under similar load conditions.
