R1112N SERIES

LOW NOISE 150mA LDO REGULATOR

NO.EA-059-130409

OUTLINE

The R1112N 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 R1112N 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.

FEATURES

• Supply Current................................................................Typ. 100μA

• Standby Current ............................................................Typ. 0.1μA

• Dropout Voltage ..............................................................Typ. 0.19V (I^OUT=100mA 3.0V Output type)

• Ripple Rejection..............................................................Typ. 80dB(f=1kHz)

• Temperature-Drift Coefficient of Output Voltage.............Typ. ±100ppm/°C

• Line Regulation...............................................................Typ. 0.05%/V

• Output Voltage Accuracy.................................................±2.0%

• Excellent Dynamic Response

• Package ........................................................................SOT-23-5(Mini-mold)

• Output Voltage ................................................................1.5V to 5.0V (0.1V steps)

(For other voltages, please refer to MARK INFORMATIONS.)

• Built-in chip enable circuit ( 2 types; A: active “Low”, B: active “High”)

• Pin-out.............................................................................Similar to the LP2980/LP2985

• Built-in fold-back protection circuit..................................Typ.30mA (Current at short mode)

• Ceramic capacitors recommended to be used with this IC

APPLICATIONS

• Power source for cellular phones such as GSM, CDMA and various kinds of PCSs.

• Power source for electrical appliances such as cameras, VCRs and camcorders.

• Power source for battery-powered equipment.
