1. Operating voltage; since the regulator is bootstrapped to the output, once started, the AS1326 operates down to

2. Startup is tested with the circuit shown in Figure 25 on page 14.

3. Defines maximum step-up ratio.

4. The regulator is in startup mode until this voltage is reached. Caution: Do not apply full load current until the

device output > 2.3V.

5. Supply current into pin OUT. This current correlates directly to the actual battery-supply current, but is reduced

in value according to the step-up ratio and efficiency.

6. ON and ONN have a hysteresis of typically 0.15V.
