TPS71256DRCR Equivalent & Substitute Parts

Part Overview

The TPS71256DRCR is a linear voltage regulator IC from Texas Instruments designed for positive fixed output applications. It delivers 250mA output current at a fixed 2.8V output with dual regulator configuration in a compact 10-VSON (3x3) surface mount package. The device integrates enable control, power good monitoring, and comprehensive protection features including over-temperature, reverse polarity, and under-voltage lockout protection.

The TPS71256DRCR is classified as obsolete. Identifying equivalent substitute parts is essential for design continuity, procurement flexibility, and long-term product support when original inventory becomes unavailable.

Substitute Part Grouping Explanation

Substitution of the TPS71256DRCR is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters define valid substitutes:

  • Output voltage: 2.8V fixed
  • Maximum output current: 250mA
  • Maximum input voltage: 5.5V
  • Dual regulator configuration (2 outputs)
  • Package type: 10-VFDFN Exposed Pad
  • Surface mount technology
  • Control features: Enable and Power Good functions
  • Protection: Over-temperature, reverse polarity, and UVLO protection
  • Operating temperature range: -40°C to 125°C
  • PSRR specification: 59dB ~ 54dB (120Hz)

The TPS71256DRCT meets all these criteria and qualifies as a parametric equivalent substitute.
