LOW NOISE 150mA LDO REGULATOR

R1111N SERIES

■ OUTLINE

The R1111N 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 R1111N 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(I^OUT=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 Output Voltage Accuracy..................................±2.0%

Excellent Line Transient Response and Load Transient Response

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: “L” active , B: “H” active)

Pinout ........................................................................Similar to the LP2980

■ APPLICATIONS

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

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

Power source for battery-powered equipment.
