Notes: (1) Tlow = 0 °C , Thigh = +125 °C
(2) Imax = 0.5 A , Pmax
(3) Load and line regulation are specified at constant junction tempereture. 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, connected between the adjustment 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.
