Substitute Part Grouping Explanation

Substitution for the LP3982IMM-2.82/NOPB is determined by the following critical parameters:

  • Fixed output voltage of 2.82V
  • Maximum output current of 300mA
  • Maximum input voltage of 6V
  • Maximum dropout voltage of 0.22V @ 200mA
  • Surface mount package compatibility (8-VSSOP)
  • Operating temperature range of -40°C to 85°C
  • Protection features: Over Current, Over Temperature, Reverse Polarity
  • Enable control feature

The LP3982IMMX-2.82/NOPB from Texas Instruments meets all these electrical and mechanical specifications and serves as a parametric equivalent. The primary distinction is packaging format: the substitute is supplied in Tape & Reel (TR) configuration versus the original tube packaging, and product status transitions from obsolete to active.
