The R1122N 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 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 is SOT-23-5 (Mini-mold) package , high density mounting of the ICs on boards is possible.

The R1122N Series are CMOS-based LDO regulators featuring 150mA output. High ripple rejection and excellent load transient response of the series make the product ideally suited for use in power source for hand-held communication equipment. The polarity of the CE pin can be selected. Ceramic capacitors can be used.

The R1121N Series is a CMOS-based voltage regulator IC with high output voltage accuracy, extremely low supply current, low ON-resistance, and high Ripple Rejection.

The R1118x series are CMOS-based voltage regulator ICs with ultra low supply current (Typ.5.5μA), and remarkable improved transient response compared with the conventional low supply current voltage regulator. The supply current of these ICs is automatically shifts between fast mode and low power mode, it depending on the load current. The current threshould is fixed internally. R1118x shifts from low power mode to fast response mode at IOUT=7mA (Typ.) and shifts fast response mode to low power mode at IOUT=2mA (Typ.). These ICs are capable of the low input voltage (Min.1.4V) and the output voltage range from 0.8V is possible. The output voltage of R1118x is fixed in the IC. Each of these ICs consists of a voltage reference unit, an error amplifier, a resister net for setting output voltage, a current limit circuits for over-current. A standby mode with ultra low supply current can be realized with the chip enable function. Since the packages for these ICs are SOT-23-5 (Limited) and DFN(PLP)1612-4B, therefore high density mounting of the ICs on boards is possible.

R1118K series are CMOS-based auto mode switching LDO regulators featuring 150mA output. In auto switching mode, the operation can switch automatically to fast response mode or low power mode of the ECO function according to output current. (Automatic switching to fast response mode under IOUT > 7mA conditions or to low power mode under IOUT < 2mA conditions.) In lower power mode, supply current is as low as 5.5μA. In fast response mode, ripple rejection is 70dB and noise is low. R1118K requires neither ECO pin for switching mode nor microcontroller pin. R1118K supports low voltage, featuring input voltage from 1.4V and output voltage from 0.8V. Standby mode and auto-discharge function are also available (see Selection Guide). Ceramic capacitors can be used.

The R1116x Series are CMOS-based voltage regulator ICs with high output voltage accuracy, low supply current, low on Resistance, and high ripple rejection.

The R1116x Series are CMOS-based seamless LDO regulators featuring 150mA output. Ricoh unique seamless technology smoothly changes transient response according to the output current without switching to a low power mode. Thus, R1116x offers an ultra low supply current in the smaller output current range which is lower than the one of R1114x (Typ. 75μA). Additionally, this product can reach low supply current without changing mode only by using the ECO pin, which is required by R1162x Series (Typ. 5.5μA). The CE pin is capable of putting the product into standby mode. The version with an auto-discharge function is also available. The pin-out meets the standard requirements. Ceramic capacitors can be used.

The R1114x Series are CMOS-based voltage regulator ICs with high output voltage accuracy, low supply current, low ON-resistance, and high ripple rejection.

The R1114x Series are CMOS-based LDO regulators featuring 150mA output. High ripple rejection and excellent load transient response of the series make the product ideally suited for use in power source for hand-held communication equipment.

The R1111N series are CMOS-based voltage regulator ICs with high output voltage accuracy, extremely low supply current, low ON-resistance, and high Ripple Rejection.
