LOW NOISE 150mA LDO REGULATOR

R1122N SERIES

n 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.

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

n FEATURES

Ultra-Low Supply Current.................................................TYP. 100mA

Standby Mode ...................................................................TYP. 0.1mA

Low Dropout Voltage ........................................................TYP. 0.19V (I^OUT= 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.

n 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.
