5A Low drop positive voltage regulator adjustable and fixed  
Features  
Typical dropout 1.3V (at 5A)  
Three terminal adjustable or fixed output  
voltage 1.8V, 2.5V, 3.3V.  
Guaranteed output current up to 5A  
DPAK  
TO-220  
Output tolerance 1ꢀ at 25°C and 2ꢀ in full  
temperature range for the "A" version  
Output tolerance 2ꢀ at 25°C and 3ꢀ ꢁn full  
temperature range internal power and thermal  
limit  
D2PAK  
Wide operating temp. range -40°C to 125°C

Package available: TO-220, D PAK, DPAK  
better performances in term of drop and output  
tolerance. A 2.85V output version is suitable for  
SCSꢁ-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.  
Pinout compatibility with standard adjustable  
VREG  
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  
he older 3-terminal adjustable regulators but has  
2
The devices are supplied in TO-220, D PAK and  
DPAK. On chip trimming allows the regulator to  
reach a very tight output voltage tolerance, within  
1ꢀ at 25°C for "A" version and 2ꢀ at 25°C for  
standard version.
