TPS70348PWPR Equivalent & Substitute Parts

Part Overview

The TPS70348PWPR is a linear voltage regulator IC from Texas Instruments designed for power management applications. It provides dual positive fixed outputs of 3.3V and 1.5V with output currents of 1A and 2A respectively. The device is housed in a 24-HTSSOP surface mount package and is currently in active production status. Alternative models may be required due to inventory constraints, application-specific performance needs, or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS70348PWPR is determined by strict equivalence across the following critical parameters:

• Dual output configuration with fixed voltage levels of 3.3V and 1.5V
• Output current ratings of 1A and 2A
• Maximum input voltage of 6V
• Maximum dropout voltage of 0.25V @ 1A
• Identical control features: Enable, Power Good, Reset, Sequencing
• Identical protection features: Over Current, Over Temperature, Reverse Polarity, Under Voltage Lockout (UVLO)
• Operating temperature range of -40°C ~ 125°C
• 24-HTSSOP surface mount package
• Active product status
• ROHS3 compliance

The TPS70448PWPR meets all these criteria and is classified as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the TPS70348PWPR and TPS70448PWPR are active products from Texas Instruments with identical electrical and mechanical specifications. Both devices are ROHS3 compliant and carry the same MSL rating of 2 (1 Year), ensuring equivalent environmental and regulatory compliance. Selection between these parts may be based on inventory availability, lead time, or supply chain logistics, as they are functionally interchangeable for all specified applications.

Frequently Asked Questions (FAQ)

Q: Can the TPS70448PWPR directly replace the TPS70348PWPR in existing designs?

A: Yes. The TPS70448PWPR is a parametric equivalent with identical electrical specifications, output voltage levels, current ratings, control features, protection features, and package configuration. No design modifications are required.

Q: Are the pin configurations identical between these parts?

A: Both devices use the 24-HTSSOP surface mount package with identical dimensions (0.173", 4.40mm Width). Pin compatibility is maintained for direct substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the TPS70348PWPR and TPS70448PWPR are ROHS3 compliant with MSL rating 2 (1 Year), ensuring equivalent regulatory and environmental compliance.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is based on matching dual output configuration, fixed voltage levels (3.3V and 1.5V), output currents (1A and 2A), maximum input voltage (6V), dropout voltage (0.25V @ 1A), control and protection features, operating temperature range (-40°C ~ 125°C), package type (24-HTSSOP), and active product status.

Q: Are there any differences in quiescent current or PSRR performance?

A: No. Both parts have identical quiescent current specifications (250 µA) and PSRR performance (65dB at 1kHz, 60dB at 1kHz).
