LD1085 - 3A low drop positive voltage regulator

Description

The LD1085 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.

Features

  • Typical dropout 1.3 V (at 3 A).
  • Three terminal adjustable or fixed output voltage 1.8 V, 2.5 V, 3.3 V, 5 V.
  • 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, D²PAK, D²PAK/A.
  • Pinout compatibility with standard adjustable VREG.

LD1085 3 A low drop positive voltage regulator: adjustable and fixed TO-220 TO-220FP Datasheet - production data Unlike PNP regulators, where a part of the output current is wasted as quiescent current, the LD1085 quiescent current flows into the load, thus increase efficiency. Only a 10 µF minimum capacitor is need for stability. The device is supplied in TO-220, TO-220FP, D²PAK and D²PAK/A packages. On-chip trimming allows the regulator to reach a very tight output voltage tolerance, within ± 1% at 25 °C. D²PAK D²PAK/A Features • Typical dropout 1.3 V (at 3 A) • Three terminal adjustable or fixed output voltage 1.8 V, 2.5 V, 3.
