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, VDD > 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 VDD to GND.
Note 6: Specifications to -40°C are guaranteed by design and not production tested.
