Operating Ratings

Junction Temperature

-40°C to 125°C

Ambient Temperature Range, TA

(3)

-40°C to 85°C

(3)

The maximum ambient temperature (TA(max)) is dependant on the maximum operating junction temperature (TJ(max-op) = 125°C), the

maximum power dissipation of the device in the application (PD(max)), and the junction to ambient thermal resistance of the part/package

in the application (

θJA), as given by the following equation: TA(max) = TJ(max-op) - (θJA × PD(max)).

(1)

Absolute Maximum Ratings are limits beyond which damage can occur. Operating Ratings are conditions under which operation of the

device is ensured. Operating Ratings do not imply ensured performance limits. For ensured performance limits and associated test

conditions, see the Electrical Characteristics tables.

(2)

Junction to ambient thermal resistance is dependant on the application and board layout. In applications where high maximum power

dissipation is possible, special care must be paid to thermal dissipation issues in board design.

Electrical Characteristics

(1) (2)

Unless otherwise noted, VEN = 950mV, VIN = VOUT + 1.0V, or 2.0V, whichever is higher, where VOUT is the higher of VOUT1 and

VOUT2. CIN = 1 µF, IOUT = 1 mA, COUT1 = COUT2 = 1.0µF.

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.

(1)

All Voltages are with respect to the potential at the GND pin.

(2)

Min Max limits are ensured by design, test or statistical analysis. Typical numbers are not ensured, but do represent the most likely

norm.

(3)

VIN(MIN) = VOUT(NOM) + 0.5V, or 2.0V, whichever is higher.

(4)

Dropout voltage is voltage difference between input and output at which the output voltage drops to 100mV below its nominal value.

This parameter only for output voltages above 2.0V
