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-

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 Cor-

poration’s in-house Class S flow-to-yield circuits usable

in stringent military applications.
