DESCRIPTION

The KD1084 is a LOW DROP Voltage Regulator able to provide up to 5A of Output Current. Dropout is guaran teed at a maximum o f 1.5V at the maximum output current, dec reasing at lower loads. The KD 1084 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 KD1084 quiescen t current flows into the load, so increase efficiency. Only a 10µF minimum capacitor is need for stability. The devices are supplied in TO-220, D

PAK/A and DPAK. On chip trimming allows the regulator to reach a very tight output voltage tolerance, within ±1% at 25°C for "A" vers ion and ±2% at 25°C for standard version.
