  • The LD1084 is a low-drop voltage regulator providing up to 5 A of output current. Dropout is guaranteed at a maximum of 1.5 V at the maximum output current, decreasing at lower loads. The LD1084 is pin-to-pin compatible with the older 3-terminal adjustable regulators, but it has better performances in terms of drop and output tolerance.

    Unlike PNP regulators, where a part of the output current is wasted as quiescent current, the LD1084 quiescent current flows into the load, so to increase the efficiency. A minimum capacitor of 10 μF is needed for stability.
    The device is supplied in TO-220. The on-chip trimming allows the regulator to reach a very tight output voltage tolerance, within ± 1% at 25 °C.

    Key Features

    • Typical dropout 1.3 V (at 5 A)
    • Three-terminal adjustable output voltage
    • Guaranteed output current up to 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
    • Pinout compatibility with standard adjustable VREG
