R1140Q151B-TR 製品詳細

OUTLINE

The R1140Q Series are voltage regulator ICs with high output voltage accuracy, 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 for setting Output Voltage, 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 R1140Q 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 internally fixed with high accuracy. Since the package for these ICs is SC-82AB (Super Mini-mold) package, high density mounting of the ICs on boards is possible.



FEATURES

• Ultra-Low Supply Current ................................................... TYP. 75µA

• Standby Mode ....................................................................... TYP. 0.1µA

• Low Dropout Voltage ........................................................... TYP. 0.15V (IOUT=100mA Output Voltage=3.0V Type)

• High Ripple Rejection .......................................................... TYP. 75dB (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 Dynamic Response

• Small Package....................................................................... SC-82AB (Super Mini-mold)

• Output Voltage...................................................................... Stepwise setting with a step of 0.1V in the range of 1.5V to 4.0V is possible

• Built-in chip enable circuit (B/D: active high)

• Built-in fold-back protection circuit..................................... TYP. 40mA (Current at short mode)



APPLICATIONS

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

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

• Power source for battery-powered equipment.
