LOW NOISE 150mA LDO REGULATOR  
R1121N SERIES  
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 are SOT-23-5 (Mini-mold) package, high density mounting of the ICs on boards is possible.  
FEATURES  
Ultra-Low Supply Current.................................................TYP. 35µA  
Standby Mode ...................................................................TYP. 0.1µA  
Low Dropout Voltage ........................................................TYP. 0.2V (IOUT = 100mA)  
High Ripple Rejection.......................................................TYP. 70db (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”)  
Pinout ................................................................................Similar to the TK112, TK111  
APPLICATIONS  
Power source for cellular phones such as GSM, CDMA and various kind of PCSs.  
Power source for domestic appliances such as cameras, VCRs and camcorders.  
Power source for battery-powered equipment.
