Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AP7370-30WR-7 are identified within the AP7370 base product family. Substitution is valid when the following critical parameters remain identical:

• Output voltage (fixed): 3V
• Output current rating: 300mA
• Input voltage maximum: 18V
• Dropout voltage: 0.6V @ 100mA
• Quiescent current: 2.5 µA
• Package type: SOT-25 (SC-74A, SOT-753)
• Operating temperature range: -40°C ~ 125°C (TJ)
• Protection features: Over Current, Over Temperature, Reverse Current, Short Circuit
• Compliance certifications: RoHS3, REACH Unaffected

The identified substitutes—AP7370-30W5-7 and AP7370-30WW-7—maintain all electrical and mechanical specifications, differing only in packaging tape configuration (W5 and WW designations), which do not affect functional performance or circuit compatibility.

Frequently Asked Questions (FAQ)

Q: Can AP7370-30W5-7 and AP7370-30WW-7 be used as direct replacements for AP7370-30WR-7?

A: Yes. All three parts share identical electrical specifications, output voltage, current rating, input voltage range, dropout voltage, operating temperature range, and package type (SOT-25). The suffix designations (WR, W5, WW) indicate tape configuration only and do not affect circuit functionality or pin compatibility.

Q: What is the difference between the WR, W5, and WW designations?

A: These designations refer to the tape and reel packaging configuration used for automated assembly. They do not affect the electrical performance or physical dimensions of the component itself.

Q: Are all three parts RoHS3 compliant?

A: Yes. AP7370-30WR-7, AP7370-30W5-7, and AP7370-30WW-7 are all RoHS3 compliant with MSL rating of 1 (Unlimited).

Q: What protection features are included in these regulators?

A: All variants include Over Current, Over Temperature, Reverse Current, and Short Circuit protection.

Q: What is the maximum dropout voltage at rated output current?

A: The maximum dropout voltage is 0.6V at 100mA for all three part numbers.

Q: Can these parts operate across the full temperature range in all applications?

A: All variants are rated for -40°C to 125°C junction temperature operation. Application-specific thermal management must be evaluated based on circuit design and ambient conditions.
