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