Notes

Test Conditions unless otherwise stated:

VIN = 1.5 to 35V, or Maximum Input, whichever is less.

IO = 10mA to 3A.

These specifications are only applicable for power dissipations of 30 Watts over a limited range of VIN – VOUT.

Over Temp. = Over specified Junction Temperature Range (See Absolute Maximum Ratings).

Low duty cycle pulse test with Kelvin connections required. Changes in output voltage are covered under the specification

for thermal regulation.

Bandwidth of 10Hz to 10kHz.

120Hz input ripple, 15V = 64dB min. COUT (CADJ) = 25mF.
