| RH1086M 0.5A and 1.5A Low Dropout Positive Adjustable Regulators DESCRIPTIO ABSOLUTE AXI U RATI GS PRECONDITIONI G 100% Thermal Limit Burn-In The RH1086M is pin compatible with older 3-terminal regulators. A 10F 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. , LTC and LT are registered trademarks of Linear Technology Corporation.

UU U 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 inputto-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. Power Dissipation..............................

Line and load regulation are measured at a constant junction temperature by low duty cycle pulse testing. Note 2: Line and load regulation are guaranteed up to the maximum power dissipation of 15W for RH1086MK and 3W for the RH1086MH. Power dissipation is determined by the input/output differential voltage and the output current. Guaranteed maximum power dissipation will not be available over the full input/output voltage range. Note 3: Dropout voltage is specified over the full output current range of the device. Test points and limits are shown on the Dropout Voltage curve in the LT (R)1086 data sheet. Note 4: Guaranteed by design, characterization, or correlation to other tested parameters. Note 5: IFULL LOAD is defined in the Current Limit curves in the standard data sheet. For compliance with 883 revision C current density specifications, the RH1086MK is derated to 1A.
