L4987CPT50TR - Very low drop voltage regulators

Download the L4987CPT50TR datasheet PDF. This datasheet also covers the L4987CPT33TR variant, as both devices belong to the same very low drop voltage regulators family and are provided as variant models within a single manufacturer datasheet.

General Description

soThe L4987 is a very low drop regulator available bin PPAK.

The very low drop-voltage (0.5 V Max at O200 mA) and the very low quiescent current make -it particularly suitable for low noise, low power t(s)applications, and in battery powered systems.

Key Features

  • Very low dropout voltage (0.25 V typ. ).
  • Dropout control flag.
  • Very low quiescent current.
  • (Typ. 90 mA in OFF Mode, 500 mA in ON Mode).
  • Output current up to 200 mA PPAK.
  • Logic-controlled electronic shutdown t(s).
  • Output voltages of 3.3 V, 5 V.
  • Internal current and thermal limit uc.
  • Only 2.2 µF for stability rod.
  • Available in ± 2% selection at 25°C P.
  • Supply voltage rejection: 70 dB (typ. ) lete.
