RH1086M - 0.5A and 1.5A Low Dropout Positive Adjustable Regulators

The RH1086M positive adjustable regulator is designed to provide 0.5A for the H package and 1.5A for the K package 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 RH1086M 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.

The wafer lots are processed to Linear Technology Corporation’s in-house Class S flow-to-yield circuits usable in stringent military applications.

Linear Technology partners with third party vendors who assemble and test packaged products with LTC RH Dice inside.
