DESCRIPTION
The RH1084 positive adjustable regulator is designed to
provide 5A 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 trim-
ming adjusts the output voltage to 1%. Current limit is
also trimmed, minimizing the stress on both the regulator
and power source circuitry under overload conditions.
The RH1084 is pin compatible with older 3-terminal regu-
lators. A 10μF output capacitor is required on these new
device. However, this is usually included in most regulator
designs.
The wafer lots are processed to Linear Technology
Corporation’s in-house Class S flow-to-yield circuits
usable in stringent military applications.
