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 guaran-

teed at a maximum of 1.5V at maximum output current,

decreasing at lower load currents. On-chip trimming ad-

justs 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 10

designs.

The wafer lots are processed to Linear Technology

Corporation’s in-house Class S flow-to-yield circuits us-

able in stringent military applications.
