TPS70758PWPR Equivalent & Substitute Parts

Part Overview

The TPS70758PWPR is a linear voltage regulator IC from Texas Instruments designed for dual-output power management applications. This device provides positive fixed outputs at 3.3V and 2.5V with output currents of 250mA and 125mA respectively. The part is classified as obsolete, making identification of suitable substitutes essential for ongoing design support and production continuity. Active equivalent models maintain identical electrical and mechanical specifications while offering current availability and extended product lifecycle support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPS70758PWPR is determined by strict equivalence across the following critical parameters:

• Dual positive fixed output voltage configuration (3.3V and 2.5V)
• Output current capability (250mA primary, 125mA secondary)
• Maximum input voltage rating (6V)
• Dropout voltage performance (0.14V @ 250mA)
• Quiescent current specification (230 µA)
• Control and protection feature set (Enable, Power Good, Reset, Sequencing, Over Current, Over Temperature, Reverse Polarity, UVLO)
• Operating temperature range (-40°C ~ 125°C)
• Package form factor (20-PowerTSSOP)
• Surface mount technology compatibility

The TPS70758PWP qualifies as a direct substitute based on complete alignment with all electrical specifications and mechanical packaging requirements. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The TPS70758PWP is the direct equivalent for the obsolete TPS70758PWPR. Both devices are manufactured by Texas Instruments and share identical electrical performance characteristics and mechanical packaging specifications. The TPS70758PWP maintains active product status, ensuring continued availability and manufacturer support. Both parts comply with ROHS3 and REACH requirements, with identical MSL ratings and operating temperature specifications. Selection between these parts is determined by packaging format requirements: the TPS70758PWP is supplied in tube packaging, while the original part was supplied in tape and reel format. For applications requiring tape and reel packaging, component procurement should specify the TPS70758PWP with appropriate packaging conversion or direct reel availability from the manufacturer.

Frequently Asked Questions (FAQ)

Q: Can the TPS70758PWP directly replace the TPS70758PWPR in existing designs?

A: Yes. The TPS70758PWP is electrically and mechanically identical to the TPS70758PWPR. All electrical specifications, output voltages, current ratings, control features, and protection mechanisms are equivalent. The device occupies the same 20-PowerTSSOP package footprint and operates across the same temperature range. No circuit modifications are required.

Q: What is the primary difference between these two part numbers?

A: The TPS70758PWPR is classified as obsolete, while the TPS70758PWP maintains active product status. The packaging format differs: TPS70758PWPR was supplied in tape and reel format, while TPS70758PWP is supplied in tube packaging. The electrical and mechanical specifications are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical ROHS3 compliance, REACH status, and MSL ratings. Both operate across the same temperature range (-40°C ~ 125°C) and carry the same moisture sensitivity level classification.

Q: What packaging considerations apply when switching from TPS70758PWPR to TPS70758PWP?

A: The primary consideration is packaging format. The TPS70758PWP is supplied in tube packaging rather than tape and reel. Manufacturing processes may require adjustment if automated tape and reel handling is specified. Contact the manufacturer or authorized distributor to confirm tape and reel availability for the TPS70758PWP if required for production automation.

Q: Are the pin configurations and PCB footprints identical?

A: Yes. Both parts use the 20-PowerTSSOP package with identical pin assignments and mechanical dimensions (0.173" width, 4.40mm). PCB layouts and footprints are directly compatible without modification.
