RH1086M

RH1086M 0.5A and 1.5A Low Dropout Positive Adjustable Regulators DESCRIPTION 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 inputoutput 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.

Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: See thermal regulation specifications for changes in output voltage due to heating effects. Line and load regulation are measured at a constant junction temperature by low duty cycle pulse testing. Note 3: 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 4: 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®1086 data sheet. Note 5: Guaranteed by design, characterization, or correlation to other tested parameters. Note 6: 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. rh1086mfc 3 RH1086M TABLE 2: ELECTRICAL TEST REQUIREMENTS MIL-STD-883 TEST REQUIREMENTS Final Electrical Test Requirements (Method 5004) Group A Test Requirements (Method 5005) Group C and D End Point Electrical Parameters (Method 5005) *PDA applies to subgroup 1.
