ELECTRICAL CHARACTERISTICS

LOAD
= 0mA,
T
A
= 0°C to +85°C
, unless otherwise noted.) (Note 6)
Note 1:
When bootstrapped, an internal low-voltage oscillator drives the EXT1 pin rail-to-rail for low supply voltages.
Note 2:
For non-bootstrapped operation, V
DD
> 2.7V is required to allow valid operation of all internal circuitry.
Note 3:
For adjustable output voltages, see the Set the Output Voltage section.
Note 4:
Measured with LBI falling. Typical hysteresis is 15mV.
Note 5:
EXT1 and EXT2 swing from V
DD
to GND.
Note 6:
Specifications to -40°C are guaranteed by design and not production tested.
