The KD1084xx is a low drop voltage regulator able to provide 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 KD1084xx is pin to pin compatible with he older 3-terminal adjustable regulators but has better performances in term of drop and output tolerance.
A 2.85 V 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 KD1084xx quiescent current flows into the load, so increase efficiency. Only a 10 µF minimum capacitor is need for stability.
The devices are supplied in D2PAK and DPAK. On chip trimming allows the regulator to reach a very tight output voltage tolerance, within ±1% at 25 for "A" version and ± 2 % at 25 for standard version.
