NOTES:

6. VOx = 0.98*VOx(NOM); Valid for VOx greater than 1.85V.

7. Parts are 100% tested at +25°C. Temperature limits established by characterization and are not production tested.

Electrical Specifications

Unless otherwise noted, all parameters are guaranteed over the operational supply voltage and temperature

range of the device as follows:

TA = -40°C to +85°C; VIN = (VO + 1.0V) to 6.5V with a minimum VIN of 2.3V; CIN = 1µF; CO = 1µF;

CBYP = 0.01µF. (Continued)
