The LD1085DT25R 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 LD1085DT25R 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 LD1085DT25R 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.
