RH1086M
0.5A and 1.5A Low Dropout
Positive Adjustable Regulators
DESCRIPTIO
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 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 us-
able in stringent military applications.
