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.
Typical Operating Characteristics
(L = 22μH, C IN = 47μF, C OUT = 47μF ?? 0.1μF, C REF = 0.1μF, T A = +25°C, unless otherwise noted.)
