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.
