The LD1085xx is a low drop voltage regulator able to provide up to 3A of output current. Dropout is guaranteed at a maximum of 1.2V at the maximum output current, decreasing at lower loads. The LD1085xx is pin to pin compatible with the older 3-terminal adjustable regulators, but has better performances in term of drop and output tolerance.
A 2.85V output version is suitable for SCSI-2 active termination. Unlike PNP regulators, where a part of the output current is wasted as quiescent current, the LD1085xx quiescent current flows into the load, so increase efficiency. Only a 10µF minimum capacitor is need for stability.
The device is supplied in TO-220, TO-220FP, DPAK, D²PAK and D²PAK/A. On chip trimming allows the regulator to reach a very tight output voltage tolerance, within ±1% at 25 °C.
The LD1085xx is available as Automotive Grade in TO-220FP package only, for the option of adjustable output voltage whose commercial part number is shown in the Table 11 (order codes). This device is qualified according to the specification AEC-Q100 of the Automotive market, in the temperature range -40 °C to 125 °C, and the statistical tests PAT, SYL, SBL are performed
