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

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
10µF minimum capacitor is need for stability.
The devices are supplied in TO-220, D2PAK 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.
