NOTES:

6. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.

7. VOx = 0.98*VOx(NOM); valid for VOx greater than 1.85V.

range of the device as follows: TA = -40°C to 105°C; VIN = (VO + 0.5V) to 6.5V with a minimum VIN of 2.3V; CIN = 1µF; CO = 1µF; CBYP = 0.01µF;

CPOR =0.01µF. Boldface limits apply over the operating temperature range, -40°C to +105°C. (Continued) (Continued)
