nn Available in 3-Lead Plastic TO-220 and DD Packages The LT®1083 series of positive adjustable regulators are
designed to provide 7.5A, 5A and 3A with higher efficiency
than currently available devices. All internal circuitry is
designed to operate down to 1V input-to-output differential
and the dropout voltage is fully specified as a function of
load current. Dropout is guaranteed at a maximum of 1.5V
at maximum output current, decreasing at lower load currents. On-chip trimming adjusts the reference voltage to
1%. Current limit is also trimmed, minimizing the stress
on both the regulator and power source circuitry under
overload conditions. nn Applications The LT1083/LT1084/LT1085 devices are pin compatible
with older 3-terminal regulators. A 10µF output capacitor
is required on these new devices. However, this is included …
