R1121N SERIES LOW NOISE 150mA LDO REGULATOR NO.EA-058-111026 OUTLINE The R1121N Series are CMOS-based voltage regulator ICs with high output voltage accuracy, extremely low supply current, low ON-resistance, and high Ripple Rejection. 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.

Analyzer ESR Iout Ceramic Capacitor 1μF Measuring Circuit for white noise; R1121N301B The relationship between IOUT (output current) and ESR of output capacitor is shown in the graphs below. The conditions when the white noise level is under 40mV (Avg.) are indicated by the hatched area in the graph. (note: When the additional ceramic capacitors are connected to the output pin with output capacitor for phase compensation, the operation might be unstable.
