RH1085
3A Low Dropout Positive
Adjustable Regulator
DESCRIPTION ABSOLUTE MAXIMUM RATINGS The RH1085 positive adjustable regulator is designed to
provide 3A 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 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. (Note 1) The RH1085 is pin compatible with older 3-terminal
regulators. A 10μF output capacitor is required on these
new device. However, this is usually included in most
regulator designs. Power Dissipation . Internally Limited
