The RH1083M positive adjustable regulator is designed to provide 7.5A 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 RH1083M is pin compatible with older 3-terminal regulators. A 10μF output capacitor is required on this new device. However, this is usually included in most regulator designs.
Unlike PNP regulators, where up to 10% of the output current is wasted as quiescent current, the RH1083M quiescent current flows into the load, increasing efficiency.
The wafer lots are processed to our in-house Class S flow-to-yield circuits usable in stringent military applications.
Since the TO-3 package on this product cannot meet the cracked glass external visual criteria of MIL-STD-883 Method 2009, inspection for cracked glass at 100% external visual will not be performed. Instead a 100% fine/gross leak test will be performed just prior to shipment.
