  • xx … The output voltage can be designated in the range from 1.2V(12) to 6.0V(60) 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

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