Electrical Characteristics (continued)

Unless otherwise noted, VEN = 1.5 V, VIN = VOUT + 1 V, CIN = 1 µF, IOUT = 1 mA, COUT = 1 µF, CBYPASS = 0.01 µF. Typical

(TYP) values and limits apply for TJ = 25°C; minimum (MIN) and maximum (MAX) apply over the full temperature range for

operation,

−40 to +125°C, unless otherwise specified in the Test Conditions.
