R1163 Series
Manual ECO Mode Shift 150mA Voltage Regulator (LDO Regulator) with Reverse Current Protection

Product Specifications

The R1163 Series are CMOS-based manual mode switching LDO regulators with ECO pin featuring 150mA 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 built-in reverse current protection circuit prevents the current flow from VOUT to VDD when VOUT is higher than VDD. This feature makes the product ideally suited for backup circuit. Standby mode and auto-discharge function are also available.

  • xx … The output voltage can be designated in the range from 1.5V(15) to 5.0V(50) in 0.1V steps.
  • # … The auto discharge function at off state are options as follows.
    B: without auto discharge function at off state
    D: with auto discharge function at off state
    E: without auto discharge function at off state, ECO logic reverse type (Low Power mode at ECO="H")

* Auto-discharge function quickly lowers the output voltage to 0 V, when the chip enable signal is switched from the active mode to the standby mode, by releasing the electrical charge accumulated in the external capacitor.
