ELECTRICAL CHARACTERISTICS (continued)
(VBATT = 2V, FB = OUT, RL =
∞, TA = -40°C to +85°C, unless otherwise noted.) (Note 4)
Note 1: Start-up voltage operation is guaranteed with the addition of a Schottky MBR0520 external diode between the input and
output.
Note 2: Steady-state output current indicates that the device maintains output voltage regulation under load. See Figures 5 and 6.
Note 3: Device is bootstrapped (power to the IC comes from OUT). This correlates directly with the actual battery supply.
Note 4: Specifications to -40°C are guaranteed by design, not production tested.
