Features & Applications
The LD1086D2TTR is a low drop voltage regulator capable of providing up to 1.5 A of output current. Dropout is guaranteed at a maximum of 1.2 V at the maximum output current, decreasing at lower loads. The LD1086xx is pin-to-pin compatible with older 3-terminal adjustable regulators, but has better performance in terms of drop and output tolerance.

The 2.85 V output version is suitable for SCSI-2 active terminations. Unlike PNP regulators, where a part of the output current is wasted as quiescent current, the LD1086xx quiescent current flows into the load, increasing efficiency. Only a 10 μF (minimum) capacitor is needed for stability. The device is available in a TO-220, D²PAK, D²PAK/A or DPAK package. On-chip trimming allows the regulator to reach a very tight output voltage tolerance; within ±1% at 25°C.

Features:

  • Typical dropout: 1.3 V at 1.5 A
  • Three-terminal adjustable or fixed output voltage: 1.5 V, 1.8 V, 2.5 V, 3.3 V, 5 V, 12 V
  • Automotive grade (adjustable VOUT in TO-220 and DPAK packages only)
  • Output current guaranteed up to 1.5 A
  • Output tolerance: ±1% at 25 °C and ± 2% in full temperature range
  • Internal power and thermal limit
  • Wide operating temperature range -40 °C to 125 °C
  • Package available: TO-220, D²PAK, D²PAK/A, DPAK
  • Pinout compatibility with standard adjustable voltage regulators
