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

Verify the complete part number suffix, specifically 'T5G', against official onsemi documentation to confirm the specific tape-and-reel packaging and RoHS compliance status. Ensure the procurement source provides traceability for AEC-Q100 automotive grade certification. Cross-reference the manufacturer's latest datasheet to confirm availability and any potential obsolescence notices before finalizing orders.

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

Select this component when a fixed 3.3V rail is required for automotive or high-reliability industrial environments. It is suitable for applications demanding 1A load capability with minimal quiescent current. Consider the TO-252-3 package for its thermal dissipation capabilities relative to smaller SOT packages. Verify that the input voltage does not exceed the 20V absolute maximum rating under all transient conditions.

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

This part belongs to the NCV1117 series, which represents the automotive-grade variant of the popular NCP1117 LDO family. While functionally similar to commercial versions, the NCV prefix indicates adherence to stricter automotive quality and reliability standards. It serves as a direct replacement for other 3.3V LDOs in designs requiring AEC-Q100 compliance without redesigning the PCB footprint.

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

Direct pin-compatible substitutes include NCP1117DT33T5G for commercial grade applications. For alternative automotive options, verify NCV1117ST33T3G if a SOT-223 package is acceptable. Always check updated datasheets for parameter variations between manufacturing lots.
