R1161x Series

Low Voltage 300mA LDO with ECO pin

The R1161x Series are CMOS-based LDO regulators with ECO pin featuring 300mA output. By inputting control signals from the ECO

pin, the mode of the regulator can be switched to low power mode or fast response mode, thus making both active and sleep modes

available for the system. The CE pin can switch the regulator into standby mode.

FEATURES

• Output Voltage Accuracy ················± 2% (Fast mode)

± 3% (Low power mode)

• Supply Current (ISS2)^∗·················Typ. 4.5μA

(Low power mode, same as above)

• Standby Current (Istandby) ············Typ. 0.1μA (Same as above, in standby)

• Dropout Voltage (VDIF)^∗··············Typ. 0.23V (Fast mode, IOUT=300mA)

Typ. 0.24V (Low power mode, I^OUT=300mA)

• Ripple Rejection (RR)················Typ. 65dB (Fast mode, f=1kHz)

• Input Voltage Range (VIN)··········1.4V to 6.0V

• Output Voltage Range (VOUT)·····0.8V to 3.3V (internally fixed)

• Temp. coeff. of Output Voltage ·······Typ. ± 100ppm/°C

• Line Regulation·······························Typ. 0.01%/V (Fast mode)

• Fold-back Protection Circuit············Current limit Typ. 50mA

• Auto-Discharge function ·················D Version
