GUARANTEED OUTPUT CURRENT UP TO 5A OUPUT TOLERANCE ±1% AT 25°C AND ±2% IN FULL TEMPERATURE RANGE FOR THE "A" VERSION OUPUT TOLERANCE ±2% AT 25°C AND ±3% IN FULL TEMPERATURE RANGE INTERNAL POWER AND THERMAL LIMIT WIDE OPERATING TEMPERATURE RANGE -40°C TO 125°C PACKAGE AVAILABLE : TO-220, D2PAK, D2PAK/A, DPAK PINOUT COMPATIBILITY WITH STANDARD ADJUSTABLE VREG D2PAK TO-220 DPAK D2PAK/A DESCRIPTION The KD1084 is a LOW DROP Voltage Regulator able to provide up to 5A of Output Current.
Dropout is guaranteed at a maximum of 1.
5V at the maximum output current, decreasing at lower loads.
The KD1084 is pin to pin compatible with the older 3-terminal adjustable regulators, but has better performances in term of drop and output tolerance .
SCHEMATIC DIAGRAM 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 quiescent current flows into the load, so increase efficiency.
Only a 10µF minimum capacitor is need for stability.
The devices are supplied in TO-220, D2PAK, D2PAK/A 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.
