T
J
= 0 to +125°C for IP323A

P
MAX
= 25W for T–Pack (TO–220) Package.
P
MAX
= 15W for SG–Pack (TO–220SM) Package.
3) All characteristics are measured with a capacitor across the input of 0.22µF and a capacitor across the output of 0.1µF.
4) All characteristics except noise voltage and ripple rejection ratios are measured using pulse techniques (t
p
≤ 10ms , δ ≤ 5%).
5) Output voltage changes due to changes into internal temperature must be taken into account separately.
