Notes:
(1) Tlow = 0°C Thigh = 125°C
(2) Imax = 1.5A Pmax : TO-220 = 2W, TO-263 = 2W
(3) Load and line regulation are specified at constant junction temperature. Changes in Vo due to heating effects must be taken into account separately.
Pulse testing with low duty cycle is used.
(4) Selected devices with tightened tolerance reference voltage available.
(5) CAdj, when used, is connected between the addjustment pin and ground.
(6) 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.
