TPS79928YZUT Equivalent & Substitute Parts

Part Overview

The TPS79928YZUT is a linear voltage regulator IC from Texas Instruments designed for power management applications. It delivers a fixed positive output of 2.8V at 200mA with a maximum dropout voltage of 0.18V. The device is actively produced and widely used in applications requiring low-noise, low-quiescent-current regulation with integrated protection features including over-current, over-temperature, reverse polarity, and under-voltage lockout (UVLO) protection. Finding equivalent substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and optimize inventory across manufacturing operations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TPS79928YZUT are identified based on strict electrical and mechanical parameter matching. The critical parameters that determine substitution eligibility are:

• Fixed output voltage of 2.8V
• Output current capability of 200mA
• Maximum input voltage of 6.5V
• Dropout voltage specification of 0.18V @ 200mA
• Quiescent current of 60 µA
• PSRR performance of 70dB ~ 38dB (100Hz ~ 100kHz)
• Package type: 5-DSBGA
• Operating temperature range: -40°C ~ 125°C
• Identical protection feature set (Over Current, Over Temperature, Reverse Polarity, UVLO)
• Active product status
• ROHS3 compliance

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The TPS79928YZUR is a direct parametric equivalent to the TPS79928YZUT. Both parts share identical electrical specifications, the same base product number (TPS79928), and equivalent regulatory compliance status (ROHS3 Compliant, REACH Unaffected). The difference between these part numbers reflects packaging or tape configuration variants from Texas Instruments. Selection between these parts should be based on supply chain availability, inventory levels, and specific procurement requirements. Both parts are actively produced and suitable for immediate design implementation without functional or performance trade-offs.

Frequently Asked Questions (FAQ)

Q: Can TPS79928YZUR be used as a direct replacement for TPS79928YZUT?
