RT9001-25GG Equivalent & Substitute Parts

Part Overview

The RT9001-25GG is a linear voltage regulator IC manufactured by Richtek USA Inc., designed to provide a fixed 2.5V output at 600mA in a surface mount SOT-223 package. This device is classified as a Power Management (PMIC) component and maintains Active product status. Linear regulators of this specification are essential in applications requiring stable, low-noise voltage regulation with minimal component count. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the specified parameter ranges.

Substitute Part Grouping Explanation

Substitute parts for the RT9001-25GG are qualified based on the following criteria:

Fixed output voltage of 2.5V
Output current capability of 600mA minimum
Surface mount SOT-223 package compatibility
Positive fixed output configuration
Over current and over temperature protection features
Active product status
ROHS3 compliance

The AP7365-25EG-13 meets these substitution criteria. Both devices share identical output voltage, output current rating, package form factor, and protection feature set. Variations in input voltage maximum rating, dropout voltage, quiescent current, and operating temperature range are within acceptable tolerance for most applications utilizing this regulator class.

Engineering Selection Recommendations

Both the RT9001-25GG and AP7365-25EG-13 are Active status products with ROHS3 compliance and REACH Unaffected designation. The AP7365-25EG-13 demonstrates superior performance characteristics in dropout voltage (0.4V vs 0.58V) and quiescent current (80 µA vs 300 µA), with higher PSRR (65dB vs 55dB). The AP7365-25EG-13 features lower moisture sensitivity (MSL 1 vs MSL 3), providing improved handling and storage flexibility.

Selection between these devices should account for application-specific requirements regarding operating temperature range. The RT9001-25GG supports operation to 125°C, while the AP7365-25EG-13 is rated to 85°C maximum. Applications requiring the extended upper temperature range must retain the RT9001-25GG. For applications within the -40°C to 85°C range, the AP7365-25EG-13 offers equivalent functionality with enhanced electrical performance.

Frequently Asked Questions (FAQ)

Q: Can the AP7365-25EG-13 directly replace the RT9001-25GG in existing designs?

A: Direct replacement is possible for applications operating within -40°C to 85°C. Both devices share identical output voltage (2.5V), output current (600mA), SOT-223 package configuration, and protection features. Pin compatibility is maintained across the TO-261-4 and TO-261AA package designations. Applications requiring operation above 85°C must use the RT9001-25GG.

Q: What are the key differences between these regulators?

A: The primary differences are operating temperature range (RT9001-25GG: -40°C to 125°C; AP7365-25EG-13: -40°C to 85°C), dropout voltage (RT9001-25GG: 0.58V; AP7365-25EG-13: 0.4V), quiescent current (RT9001-25GG: 300 µA; AP7365-25EG-13: 80 µA), and moisture sensitivity level (RT9001-25GG: MSL 3; AP7365-25EG-13: MSL 1). Electrical output specifications and protection features remain identical.

Q: Are there package compatibility concerns?

A: Both devices utilize SOT-223 packaging with TO-261-4 and TO-261AA case designations. The supplier device package designation differs (SOT-223 vs SOT-223-3), but this reflects internal classification and does not affect PCB footprint or pin configuration compatibility.

Q: Which device should be selected for new designs?

A: For new designs not requiring operation above 85°C, the AP7365-25EG-13 is preferred due to lower dropout voltage, reduced quiescent current, and improved moisture sensitivity rating. For applications with extended temperature requirements or existing inventory constraints, the RT9001-25GG remains a valid selection.
