OUTLINE
The R1122N Series are voltage regulator ICs with high output voltage accuracy, extremely 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, 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 R1122N 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 fixed with high accuracy.
Since the package for these ICs are SOT-23-5 (Mini-mold) package, high density mounting of the ICs on boards is possible.
