DESCRIPTION

The KD1084 is a LOW DROP Voltage Regulator
able to provide up to 5A of Output Current.
Dropout is guaran teed at a maximum o f 1.5V at
the maximum output current, dec reasing at lower
loads. The KD 1084 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 quiescen t current flows into
the load, so increase efficiency. Only a 10µF
minimum capacitor is need for stability.
The devices are supplied in TO-220, 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" vers ion and
±2% at 25°C for standard version.
