These specifications are applicable for power dissipations up to 50W. Power dissipation is specified at these values up to 15-V input-

output differential. Above 15-V differential, power dissipation will be limited by internal protection circuitry. All limits (that is, the numbers

in the minimum and maximum columns) are specified to TI's AOQL (Average Outgoing Quality Level).

(2)

Typical figures are at TA = 25°C, and represent most likely parametric norms. Test limits are ensured to Texas Instruments' average

outgoing quality level (AOQL).

(3)

VIN – VOUT = 3.3 V at –55°C and 125°C.

(4)

Regulation is measured at a constant junction temperature, using pulse testing with a low duty cycle. Changes in output voltage due to

heating effects are covered under the specifications for thermal regulation.

(5)

Datalog reading in mV, 0.01% = 1.19 mV.

Family board not required for this device.
