ELECTRICAL CHARACTERISTICS (continued)

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

VOUT2. CIN = COUT = 1µF, IOUT = 1.0mA .

Typical values and limits appearing in normal type apply for TA = 25°C. Limits appearing in boldface type apply over the full

junction temperature range for operation,

−40 to +125°C.

The capacitor tolerance should be 30% or better over temperature. The full operating conditions for the application should be considered

when selecting a suitable capacitor to ensure that the minimum value of capacitance is always met. Recommended capacitor type is

X7R or X5R. (See capacitor section in Application Hints)
