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.

FEATURES
Ultra-Low Supply Current.................................................TYP. 100mA
Standby Mode ...................................................................TYP. 0.1mA
Low Dropout Voltage ........................................................TYP. 0.19V (IOUT= 100mA, 3V Output type)
High Ripple Rejection .......................................................TYP. 80dB (f = 1kHz)
Low Temperature-Drift Coefficient of Output Voltage .....TYP. ±100ppm/°C
Excellent Line Regulation .................................................TYP. 0.05%/V
High Accuracy Output Voltage..........................................±2.0%
Small Package  ..................................................................SOT-23-5 (Mini-mold)
Output Voltage ...............................................................Stepwise setting with a step of 0.1V in the range of 1.5V to 5.0V is possible.
Built-in chip enable circuit (2 Types; A: active “L”, B: active “H”)
Built-in Fold-back protection circuit .................................Short Current Typ. 30mA
Pinout ................................................................................Similar to the TK112, TK111
Ceramic Capacitors are Recommendable to be used with this IC.

APPLICATIONS
Power source for cellular phones such as GSM, CDMA, PCS and so forth.
Power source for domestic appliances such as cameras, VCRs and camcorders.
Power source for battery-powered equipment.
