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.
