ELECTRICAL CHARACTERISTICS
The q denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C.
VIN = 0.9V to 1.8V, C1 = C3 = 1µF, CIN = C2 = COUT = 10µF unless otherwise specified.

Note 1: Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
Note 2: Start-up testing is done with a 100kΩ equivalent load on VOUT.
Note 3: Currents flowing into the device are positive polarity. Currents
flowing out of the device are negative polarity.
Note 4: Commercial grade specifications are guaranteed over the 0°C to
70°C operating temperature range. In addition, commercial grade
specifications are assured over the –40°C to 85°C operating temperature
range by design, characterization and correlation with statistical process
controls. Industrial grade specifications are guaranteed and tested over the
–40°C to 85°C operating temperature range.
