DATA SHEET
LND1083/84/85
7.5 A, 5 A, 3 A Low Dropout Positive Adjustable Regulators
GENERAL DESCRIPTION
The LND1083/LND1084/LND1085 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. 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.
The LND1083/LND1084/LND1085 devices are
pin compatible with older 3 terminal regulators.
A 10µF output capacitor is required on these
new devices: however, this is usually included
in most regulator designs.
