R1114 Series
150mA Voltage Regulator (LDO Regulator)

Product Specifications

The R1114 Series are CMOS-based LDO regulators featuring 150mA output. High ripple rejection and excellent load transient response of the series make the product ideally suited for use in power source for hand-held communication equipment. The polarity of the CE pin can be selected. The auto-discharge function is also available.

  • xx … The output voltage can be designated in the range from 1.5V(15) to 4.0V(40) in 0.1V steps.
  • # … CE pin polarity and auto discharge function at off state are options as follows.
    A: "L" active, without auto discharge function at off state
    B: "H" active, without auto discharge function at off state
    D: "H" active, with auto discharge function at off state

* Auto-discharge function quickly lowers the output voltage to 0V, 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.
