OUTLINE
The R1140Q Series are voltage regulator ICs with high output voltage accuracy,
low supply current, low ON resistance, and high ripple rejection by CMOS
process. Each of these voltage regulator ICs consists of a voltage reference
unit, an error amplifier, resistors for setting Output Voltage, a current
limit circuit, and a chip enable circuit.
These ICs perform with low dropout voltage and a chip enable function. The
line transient response and load transient response of the R1140Q Series are
excellent, thus these ICs are very suitable for the power supply for hand-held
communication equipment.
The output voltage of these ICs is internally fixed with high accuracy. Since
the package for these ICs is SC-82AB (Super Mini-mold) package, high density
mounting of the ICs on boards is possible.
