Notes
1) Applies over full temperature range:–
T
J
= –55 to +150°C for IP123A / IP123 / LM123
T
J
=
0 to +125°C for IP323A
All other specifications apply at T
J
= 25°C unless otherwise stated.
2) P
MAX
= 30W for K–Pack (TO–3) , V–Pack (TO–218) and G–Pack (TO–257) Packages.
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 0.22
μ
F and a capacitor across the output of 0.1
μ
F.
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.
