*1)Condition: An Output load resistor RL is connected between VOUT and GND.
Note that the resistor RL has a resistance which makes an output current 1mA after step-up operation.
*2)The Supply Current 1 (IDD1) for IC itself is measured when the internal oscillator works continuously.
If the oscillator works intermittently, the supply current becomes smaller than the value which is written on
the above table. Measurement condition: VOUT
