产品概述
描述
The KD1084 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 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 "A" version and ± 2% at 25 °C for standard version.
