Description
The KD1084xx is a low drop voltage regulator
able to provide up to 5 A of output current.
Dropout is guaranteed at a maximum of 1.5 V at
the maximum output current, decreasing at lower
loads. The KD1084xx is pin to pin compatible with
he older 3-terminal adjustable regulators but has
better performances in term of drop and output
tolerance.
Table 1.
D2PAK
DPAK
A 2.85 V 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 KD1084xx quiescent current flows
into the load, so increase efficiency. Only a 10 µF
minimum capacitor is need for stability.
The devices are supplied in 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.
