Notes
a.
Tlow = 0_C, Thigh = 125_C
b.
Imax = 1.5 A, Pmax: TO-220 = 2 W, TO-263 = 2 W
c.
Load and line regulation are specified at constant junction temperature. Changes in VOUT due to heating effects must be taken into account separtely. Pulse
testing with low duty cycle is used.
d.
Selected devices with tightened reference voltage tolerance available.
e.
CADJ, when used, is connected between the adjustment pin and ground.
f.
Since long-term stability cannot be measured on each device before shipment, this specification is an engineering estimate of average stability from lot to lot.
