LOW NOISE 150mA LDO REGULATOR
R1121N SERIES
Rev.1.11

OUTLINE
The R1121N 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 R1121N 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 is SOT-23-5 (Mini-mold) package, high density mounting of the ICs on boards is possible.
