Semelab Plc reserves the right to change test conditions, parameter limits and package dimensions without notice. Information furnished by Semelab is believed

to be both accurate and reliable at the time of going to press. However Semelab assumes no responsibility for any errors or omissions discovered in its use.

Semelab encourages customers to verify that datasheets are current before placing orders.

1)

All characteristics are measured with a capacitor across the input of 2.2

µF and a capacitor across the output of 1.0µF.

All characteristics except noise voltage and ripple rejection ratio are measured using pulse techniques (tp ≤ 10ms, δ≤ 5%). Output voltage changes due to changes in

internal temperature must be taken into account separately.

2)

Test Conditions unless otherwise stated: PMAX = 10W for SMD , P MAX = 20W for all other package devices, IMAX = 1.0A , TJ = 25°C
