Note 1: Specifications are production tested at TA=25°C. Specifications over the -40°C to 85°C operating tem-

perature range are assured by design, characterization and correlation with Statistical Quality Controls

(SQC).

Note 2: Start-up voltage operation is guaranteed without the addition of an external Schottky diode between the

input and output.

Note 3: Steady-state output current indicates that the device maintains output voltage regulation under load.

Note 4: Device is bootstrapped (power to the IC comes from OUT). This correlates directly with the actual

battery supply.
