Typical Performance Characteristics.

Unless otherwise noted, SD = 950mV, VIN = VOUT + 1.0V, CIN = 2.2 µF, IOUT = 1 mA, COUT = 2.2 µF and CBYP = 0.1 µF.

Typical values and limits appearing in normal type apply for TJ = 27°C. Limits appearing in boldface type apply over the full

temperature range for operation,

−40 to +125°C.
