Electrical Characteristics (continued)

Unless otherwise noted, VEN = 1.2 V, VIN = VOUT + 0.5 V, or 1.8 V, whichever is higher (where VOUT is the higher of VOUT1 and

VOUT2), CIN = COUT = 1 µF, and IOUT = 1 mA. Typical values apply for TA = 25°C; minimum and maximum values apply over the

full junction temperature range for operation,

−40 to +125°C, unless otherwise specified.
