DESCRIPTION(KD1084D2M28 datasheet and pdf download):
http://www.chinaicmart.com/series-KD1/KD1084D2M28.htmlThe 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 .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
minimum capacitor is need for stability. The devices are supplied in TO-220, D PAK,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" version and ±2% at 25°C for standard version.
