PINOUT COMPATIBILITY WITH STANDARD
ADJUSTABLE VREG
insufficient heatsinking. The KD1083 is fully pin to
pin compatible with the older 3-terminal adjustable
regulators, but it has better performances in terms
of drop and output voltage precision.
On chip trimming allows the regulator to reach a
very tight output voltage tolerance, within ±2% at
25°C and 2% over the full temperature range.
Unlike voltage regulators using a PNP transistor
as series pass element in which a considerable
fraction of the output current is wasted as
quiescent current, the LD1083 quiescent current
flows almost entirely into the load, improving the
efficiency.
DESCRIPTION
The KD1083 is a low drop linear voltage regulator,
proposed both in adjustable and fixed version and
designed for use in applications requiring output
currents up to 7.5A. Dropout voltage is
guaranteed not to exceed 1.4V at maximum
output
current
while
it
decreases
at
lighter loads. The KD1083 also features an
on-chip output current limit function and a thermal
shutdown protection with hysteresis, preventing
from excessive power dissipation in case of
Only a 10µF minimum capacitor is required for
output stability.
