RH1086M_1 Datasheet, PDF (1/6 Pages) Linear Technology – 0.5A and 1.5A Low Dropout Positive Adjustable Regulators

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 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.
