Product overview
Description
The LD1085C is a low-drop voltage regulator, providing up to 3 A of output current.The dropout is guaranteed to be as low as 1.5 V at the maximum current and it decreases at lower loads. The LD1085C is pin-to-pin compatible with the old 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 LD1085C 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 DPAK. The on-chip trimming allows the regulator to reach a very tight output voltage tolerance, within ± 2% at 25 °C.
