Note 1:
Operating voltage. Since the regulator is bootstrapped to the output, once started it will operate down to 0.7V input.
Note 2:
The device is in startup mode when V
OUT
is below this value (see
Low-Voltage Startup Oscillator
section). Do not apply full
load current.
Note 3:
Supply current into the OUT and POUT pins. This current correlates directly to the actual battery-supply current, but is
reduced in value according to the step-up ratio and efficiency.
Note 4:
Minimum recommended ISET voltage in normal mode is 0.625V.
Note 5:
ONA,
