TPS77525PWPR Equivalent & Substitute Parts

Part Overview

The TPS77525PWPR is a linear voltage regulator IC from Texas Instruments designed for positive fixed output applications. It delivers 500mA output current at a fixed 2.5V output with integrated enable and reset control features, along with over-current, over-temperature, and reverse polarity protection. The main part is classified as obsolete, making substitute parts necessary for new designs and ongoing production requirements. The TPS77525PWP serves as the direct active substitute, maintaining identical electrical and mechanical specifications while offering current availability.

Key Parameters

Substitute Part Grouping Explanation

The TPS77525PWP qualifies as a direct substitute for the TPS77525PWPR based on strict electrical and mechanical parameter equivalence. Both parts share identical specifications across all critical substitution criteria: output voltage (2.5V fixed), output current (500mA), input voltage rating (10V maximum), quiescent current (125 µA), PSRR performance (60dB at 100Hz), control features (Enable, Reset), protection mechanisms (Over Current, Over Temperature, Reverse Polarity), operating temperature range (-40°C to 125°C), and physical package (20-PowerTSSOP). The substitution is valid based on matching base product number (TPS77525), identical RoHS3 compliance, equivalent MSL rating (2), and identical supplier device package designation (20-HTSSOP). The primary distinction is product status: TPS77525PWPR is obsolete while TPS77525PWP is active, and packaging format (TPS77525PWP supplied in Tube versus TPS77525PWPR in standard packaging).

Parameter Comparison

Engineering Selection Recommendations

The TPS77525PWP is the appropriate selection for applications currently using or requiring the TPS77525PWPR. The substitute part maintains full electrical and mechanical compatibility while offering the advantage of active product status and current manufacturing availability. Both parts carry ROHS3 compliance and identical MSL ratings, ensuring equivalent environmental and regulatory compliance for production and field deployment. The transition from obsolete to active status makes TPS77525PWP the standard choice for new designs and production continuity.

Frequently Asked Questions (FAQ)
