R1161 Series

Manual ECO Mode Shift Low Voltage 300mA Voltage Regulator

  • Consumer
  • RoHS

The R1161 Series are CMOS-based manual mode switching LDO regulators with ECO pin featuring 300mA output. By inputting control signals to 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.
