Features & Applications
The LD1085V is a low drop voltage regulator able to provide up to 3 A of output current. Dropout is guaranteed at a maximum of 1.2 V at the maximum output current, decreasing at lower loads. The LD1085xx is pin to pin compatible with the older 3-terminal adjustable regulators, but has better performances in term of drop and output tolerance.

A 2.85 V output version is suitable for SCSI-2 active termination. Unlike PNP regulators, where a part of the output current is wasted as quiescent current, the LD1085xx quiescent current flows into the load, so increase efficiency. Only a 10 μF minimum capacitor is need for stability. The device is supplied in TO-220, TO-220FP,DPAK, D2PAK and D2PAK/A. 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 3 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 product: adjustable VOUT only in TO-220 full pack package
  • Guaranteed output current up to 3 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, TO-220FP, DPAK, D2PAK, D2PAK/A
  • Pinout compatibility with standard adjustable VREG
