Dropout is guaranteed at a maximum of 1.5 V at the maximum output current, decreasing at lower loads. The KD1084 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 KD1084 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 °C for d o r P e t e l o s b O Table 1.
