Notes:

1/ Unless otherwise specified, these specifications apply for (Vin - Vout) = 5V, Iout = 0.5A and -55°C < Tc < +125°C.

2/ 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 specification for thermal regulation. Measurements taken at the output lead must be adjusted for lead

resistance.

3/ Not tested. Shall be guaranteed to the specified limits.

4/ Specification derated to reflect High Dose Rate (1019 condition A) to 100 krad(Si) and Low Dose Rate (1019 condition D) to 50 krad(Si),

@ +25°C.

5/ Pulsed @ < 10% duty cycle @ +25°C.
