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

0.7V input. If CLK/SEL = GND then VIN ≤ VOUT. If CLK/SEL = VOUT then VIN ≤ 0.75xVOUT.

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.
