TPS73230MDBVREP Equivalent & Substitute Parts

Part Overview

The TPS73230MDBVREP is a linear voltage regulator IC from Texas Instruments designed for positive fixed 3V output applications. This active product delivers 250mA output current in a compact SOT-23-5 surface mount package. The device is suitable for low-power applications requiring stable 3V regulation from input sources up to 5.5V. Substitute parts may be required due to inventory constraints, regional availability, or specific application requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS73230MDBVREP is determined by the following critical parameters:

• Output voltage fixed at 3V
• SOT-23-5 package compatibility
• Positive output configuration
• Surface mount mounting type
• Active product status
• ROHS3 compliance

The RT9193-30GB qualifies as a substitute based on matching output voltage (3V), identical package type (SOT-23-5), positive output configuration, and active product status. Both devices are ROHS3 compliant and suitable for surface mount applications. Variations in output current rating (250mA vs 300mA), dropout voltage, quiescent current, and operating temperature range do not disqualify substitution when the application requirements fall within the substitute's specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the TPS73230MDBVREP and RT9193-30GB are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. Selection between these devices should be based on application-specific requirements:

The TPS73230MDBVREP provides extended operating temperature range (-55°C to 125°C) and lower dropout voltage (0.15V @ 250mA), making it suitable for applications requiring wider temperature operation or minimal voltage headroom.

The RT9193-30GB offers higher output current capability (300mA vs 250mA), lower quiescent current (130 µA vs 550 µA), and superior PSRR performance (70dB ~ 50dB vs 58dB ~ 37dB), benefiting applications with higher current demands or requiring lower standby power consumption.

Both devices maintain identical output voltage (3V), maximum input voltage (5.5V), and package form factor (SOT-23-5), ensuring direct PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can RT9193-30GB replace TPS73230MDBVREP in all applications?

A: Substitution is valid when application requirements fall within the RT9193-30GB specifications. The higher output current (300mA) and lower quiescent current (130 µA) of the RT9193-30GB are compatible with designs requiring up to 250mA. However, the extended temperature range of the TPS73230MDBVREP (-55°C vs -40°C minimum) may be required for specific environmental conditions.

Q: Are the packages physically identical?

A: Both devices use the SOT-23-5 package (SC-74A designation), ensuring identical PCB footprint and pin configuration. No layout modifications are required for substitution.

Q: What are the key differences in electrical performance?

A: The RT9193-30GB features lower dropout voltage specification (0.3V @ 300mA vs 0.15V @ 250mA), higher quiescent current (130 µA vs 550 µA), and superior PSRR performance. The TPS73230MDBVREP provides lower dropout voltage at its rated current and extended temperature operation.

Q: Do both parts meet current compliance requirements?

A: Both devices are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component manufacturing and distribution.

Q: What is the moisture sensitivity consideration?

A: The TPS73230MDBVREP has MSL 1 (unlimited shelf life), while the RT9193-30GB has MSL 3 (168 hours). Storage and handling procedures should follow the respective moisture sensitivity levels.
