5A Low Dropout Positive Adjustable Regulator

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 trimming 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 regulators. 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 in-house Class S flow-to-yield circuits usable in stringent military applications.

Third Party Vendor Availability Analog Devices partners with third party vendors who assemble and test packaged products with RH Dice inside.
