Key Parameters

Substitute Part Grouping Explanation

Substitution of the PAM2301CAABADJ is determined by strict alignment of the following critical parameters:

• Topology & Function: Buck (step-down) switching regulator topology
• Output Configuration: Positive adjustable output
• Input Voltage Range: 2.5V to 5.5V minimum compatibility
• Output Voltage Range: 0.6V to 5.5V adjustable capability
• Package Type: SOT-23-5 Thin (TSOT-23-5) for mechanical and thermal compatibility
• Synchronous Rectifier: Integrated synchronous rectification capability
• Compliance: ROHS3 compliance and MSL Level 1 rating

The LTC3564ES5#TRMPBF from Analog Devices Inc. meets all substitution criteria. While it provides enhanced specifications (1.25A output current versus 800mA, 2.25MHz switching frequency versus 1.5MHz, and extended operating temperature to 125°C junction temperature), these represent functional improvements that maintain backward compatibility with PAM2301CAABADJ applications.

Parameter Comparison

Engineering Selection Recommendations

The LTC3564ES5#TRMPBF is the primary substitute for the obsolete PAM2301CAABADJ. Selection is justified on the following engineering grounds:

Product Status: The PAM2301CAABADJ is obsolete, while the LTC3564ES5#TRMPBF maintains active product status with ongoing manufacturer support and supply availability.

Compliance & Certifications: Both devices maintain ROHS3 compliance and MSL Level 1 rating, ensuring equivalent environmental and handling requirements.

Electrical Compatibility: The LTC3564ES5#TRMPBF provides identical input and output voltage ranges (2.5V to 5.5V input, 0.6V to 5.5V adjustable output) and identical package form factor (SOT-23-5 Thin), enabling direct functional substitution in existing circuit designs.

Enhanced Specifications: The LTC3564ES5#TRMPBF delivers higher output current capability (1.25A versus 800mA) and extended operating temperature range (-40°C to 125°C junction temperature versus -40°C to 85°C ambient), providing design margin for thermal and load conditions.

Supply Chain: The LTC3564ES5#TRMPBF maintains active inventory status (6186 units in stock) compared to the obsolete PAM2301CAABADJ, ensuring reliable procurement for production and field replacement applications.

Frequently Asked Questions (FAQ)

Q: Can the LTC3564ES5#TRMPBF directly replace the PAM2301CAABADJ without circuit modifications?

A: Yes. Both devices share identical input voltage range (2.5V to 5.5V), output voltage range (0.6V to 5.5V adjustable), package type (SOT-23-5 Thin), and pin configuration. The LTC3564ES5#TRMPBF operates as a direct functional substitute with no required circuit changes.

Q: What are the key differences between these two parts?

A: The LTC3564ES5#TRMPBF provides three enhancements: higher output current (1.25A versus 800mA), higher switching frequency (2.25MHz versus 1.5MHz), and extended operating temperature range (junction temperature to 125°C versus ambient to 85°C). These represent performance improvements that maintain backward compatibility.

Q: Why is the PAM2301CAABADJ listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production and support. The LTC3564ES5#TRMPBF is the recommended active equivalent for new designs and replacement applications.

Q: Are there any thermal or layout considerations when substituting these parts?

A: Both devices use identical SOT-23-5 Thin packaging, so PCB footprints and thermal layouts remain unchanged. The higher switching frequency of the LTC3564ES5#TRMPBF (2.25MHz) may require minor adjustments to filter component values, but the identical package ensures mechanical compatibility.

Q: What compliance certifications apply to both parts?

A: Both the PAM2301CAABADJ and LTC3564ES5#TRMPBF maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring equivalent environmental and handling requirements for production and field deployment.

Q: Is the LTC3564ES5#TRMPBF available in the same packaging options?

A: The LTC3564ES5#TRMPBF is supplied in Cut Tape (CT) and Digi-Reel® packaging formats. Both devices use the SOT-23-5 Thin (TSOT-23-5) case, ensuring identical mechanical compatibility with existing PCB designs.
