LX = open, T
Note 1: Once the output is in regulation, the MAX1705/MAX1706 operate down to a 0.7V input voltage.
Note 2: The device is in startup mode when V
Note 3: ONA and ONB inputs have a hysteresis of approximately 0.15V
Note 4: Specifications to -40°C to are guaranteed by design, not production tested.
