产品概述

描述

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. The LD1085 is pin-to-pin compatible with the older 3-terminal adjustable regulators, but offers better performance in terms of drop and output tolerance.

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.

  • 所有功能

    • 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
