PINOUT COMPATIBILITY WITH STANDARD  
ADJUSTABLE VREG  
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 LD1084 quiescent current flows into  
the load, so increase efficiency. Only a 10µF  
minimum capacitor is need for stability.  
The device is supplied in TO-220, D PAK and  
D PAK/A. On chip trimming allows the regulator to  
reach a very tight output voltage tolerance, within  
±1% at 25°C.  
DESCRIPTION  
The LD1084 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 LD1084 is pin to pin compatible with  
the older 3-terminal adjustable regulators, but has  
better performances in term of drop and output  
tolerance .
