LD1085D2M33R

3 A low drop positive voltage regulator: adjustable and fixed 低压差稳压器 3.3V 3.0A Positive

Description LD1085D2M33R

The LD1085D2M33R 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.
