• 300mA output current per regulator
• Maximum input voltage of 5.25V
• 8-XFDFN exposed pad package footprint compatibility
• Voltage dropout specifications within acceptable operating ranges
• Quiescent current of 140 µA
• PSRR performance of 75dB at 1kHz
• Operating temperature range of -40°C to 85°C
• Surface mount mounting type
• ROHS3 compliance and MSL Level 1 rating

The AP7345D-3028RH4-7 meets all these criteria and is identified as the manufacturer-recommended substitute.

Parameter Comparison

Engineering Selection Recommendations

The AP7345D-3028RH4-7 is the direct substitute for the AP7344D-3028RH4-7. The substitute part maintains identical electrical specifications, package footprint, and compliance certifications. The primary distinction is product status: the AP7345D-3028RH4-7 is in Active status, ensuring continued availability and supply chain support, whereas the AP7344D-3028RH4-7 is designated Last Time Buy.

Both parts are ROHS3 compliant and carry REACH Unaffected status, meeting regulatory requirements for electronic component deployment. The MSL Level 1 rating indicates unlimited shelf life under controlled storage conditions.

Frequently Asked Questions (FAQ)

Q: Are the AP7344D-3028RH4-7 and AP7345D-3028RH4-7 pin-compatible?

A: Yes. Both devices use the 8-XFDFN exposed pad package with identical pinout and footprint geometry, enabling direct PCB-level substitution without layout modifications.

Q: What is the significance of the Last Time Buy status for the AP7344D-3028RH4-7?

A: Last Time Buy designation indicates the manufacturer will no longer accept new orders after a specified cutoff date. Existing inventory may be available, but long-term supply cannot be guaranteed. Migration to the AP7345D-3028RH4-7 is recommended for new designs and ongoing production.

Q: Are there differences in control features between these parts?

A: The AP7344D-3028RH4-7 includes Enable control. The AP7345D-3028RH4-7 includes Current Limit and Enable control features. Both devices support the required enable functionality for standard applications.

Q: Do these parts have identical protection features?

A: The AP7344D-3028RH4-7 includes Over Current protection. The AP7345D-3028RH4-7 includes Short Circuit protection. Both provide fault protection mechanisms suitable for power management applications.

Q: What is the voltage dropout difference between these parts?

A: The AP7344D-3028RH4-7 specifies 0.3V @ 300mA and 0.29V @ 300mA. The AP7345D-3028RH4-7 specifies 0.3V @ 300mA for both outputs. Both values fall within acceptable operating ranges for dual-output linear regulator applications.

Q: Are moisture sensitivity and RoHS compliance identical?

A: Yes. Both parts carry MSL Level 1 (Unlimited) rating and ROHS3 compliance, meeting identical environmental and regulatory standards for component storage and deployment.
