Note 1:
Operating voltage. Since the regulator is bootstrapped to the output, once started it will operate down to 0.7V input.
Note 2:
Start-up is tested with the circuit of Figure 2.
Note 3:
In low-power mode (CLK/SEL = GND), the output voltage regulates 1% higher than low-noise mode (CLK/SEL = OUT or
synchronized).
Note 4:
The regulator is in start-up mode until this voltage is reached. Do not apply full load current.
Note 5:
Load regulation is measured from no-load to full load where full load is determined by the N-channel switch current limit.
Note 6:
Supply current from the 3.30V output is measured between the 3.30V output and the OUT pin. This current correlates
directly to the actual battery supply current, but is reduced in value according to the step-up ratio and efficiency. Set V
OUT
= 3.6V to keep the internal switch open when measuring the current into the device.
Note 7:
ONA and
ONB
have hysteresis of approximately 0.15xV
OUT
.
Note 8:
Specifications to -40°C are guaranteed by design and not production tested.
