(2) turn on time is defined as the time from the application of power until the output is within 1% of its final value. (3) determine the correct fuse size by calculating the maximum dc current drain at low line input, maximum load and then adding 20 to 25 percent. (4) no minimum load required. (5) short term stability is specified after a 30 minute warm-up at full load and with constant line, load and ambient conditions. * s r e t e m a r a p t u p n i l e d o ma 0 5 2 . 2 1 d 2 1a 0 0 2 . 5 1 d 2 1a 0 5 2 . 2 1 d 4 2a 0 0 2 . 5 1 d 4 2s t i n u e g n a r e g a t l o v n i m x a m 6 1 . 1 1 0 2 . 3 1 2 3 . 2 2 0 4 . 6 2 c d v w b z h m 0 2 - 0 , e l p p i r d e t c e l f e r p y t x a m 0 1 5 2 5 5 1 p - p a m d a o l l l u f t n e r r u c t u p n i d a o l o n p y t p y t 0 8 7 5 4 9 6 7 0 5 8 7 3 2 2 2 6 3 3 2 a m y c n e i c i f f ep y t4 65 66 69 6% y c n e u q e r f g n i h c t i w sp y t5 7z h k s m 0 0 1 , e g a t l o v r e v o t u p n i m u m i x a m e g a m a d o n x a m5 10 3c d v ) 2 ( r o r r e t u p t u o % 1 , e m i t n o - n r u tp y t3 s m e s u f d e d n e m m o c e r ) 3 ( l e d o ma 0 5 2 . 2 1 d 8 2a 0 0 2 . 5 1 d 8 2a 0 5 2 . 2 1 d 8 4a 0 0 2 . 5 1 d 8 4s t i n u e g n a r e g a t l o v n i m x a m 4 0 . 6 2 0 8 . 0 3 4 6 . 4 4 0 8 . 2 5 c d v w b z h m 0 2 - 0 , e l p p i r d e t c e l f e r p y t x a m 7 5 1 5 1 5 2 p - p a m d a o l l l u f t n e r r u c t u p n i d a o l o n p y t p y t 5 2 3 2 2 5 1 3 2 2 8 9 1 1 2 9 8 1 1 2 a m y c n e i c i f f ep y t6 68 63 66 6% y c n e u q e r f g n i h c t i w sp y t5 7z h k s m 0 0 1 , e g a t l o v r e v o t u p n i m u m i x a m e g a m a d o n x a m5 30 6c d v ) 2 ( r o r r e t u p t u o % 1 , e m i t n o - n r u tp y t3 s m e s u f d e d n e m m o c e r ) 3 ( * s r e t e m a r a p t u p t u o l e d o m a 0 5 2 . 2 1 d 4 2 a 0 5 2 . 2 1 d 2 1 a 0 5 2 . 2 1 d 8 4 a 0 5 2 . 2 1 d 8 2 a 0 0 2 . 5 1 d 4 2 a 0 0 2 . 5 1 d 2 1 a 0 0 2 . 5 1 d 8 4 a 0 0 2 . 5 1 d 8 2 s t i n u e g a t l o v t u p t u o2 1 5 1 c d v ) 4 ( t n e r r u c d e t a r n i m x a m 0 0 5 2 0 0 0 2 a m e g n a r e g a t l o v d a o l % 0 0 1 n i m p y t x a m 0 9 . 1 1 0 0 . 2 1 0 1 . 2 1 0 9 . 4 1 0 0 . 5 1 0 1 . 5 1 c d v e c n a l a b t u p t u o ) d a o l l l u f , t u p t u o s u n i m o t s u l p ( p y t x a m 6 . 0 0 . 1 6 . 0 0 . 1 % % 0 0 1 - 0 n o i t a l u g e r d a o l p y t x a m 2 0 . 0 0 1 . 0 % n o i t a l u g e r e n i l c d v x a m - n i m = n i v p y t x a m 5 0 . 0 0 1 . 0 % ) 6 ( e s n o p s e r t n e i s n a r tp y t% 1 s d e e c x e r e v e ns ) 7 ( e s n o p s e r c i m a n y dp y t0 1k a e p v m ) 8 ( n o i t c e j e r e l p p i r t u p n ip y t5 6b d w b z h m 0 2 - 0 , e s i o n p y t x a m 0 1 0 4 p - p v m t n e i c i f f e o c e r u t a r e p m e t p y t x a m 0 0 1 0 5 2 0 5 1 0 0 3 c / m p p o t n o i t c e t o r p t i u c r i c t r o h s s t u p t u o l l a r o f n o m m o c t i m i l t n e r r u c m u m i n i m s r u o h 8 , s u o u n i t n o c

(6) the transient response is specified as the time required for the output to settle from a 100% step load change (rise time of step = 2 sec.) to a 1% error band. (7) dynamic response is the peak overshoot voltage during the transient response time as defined in note 6 above. (8) the input ripple rejection is specified for dc to 120hz ripple with a modulation amplitude of 1% vin. (9) the case thermal impedance is specified as the case temperature rise over ambient per package watt dissipated. * s n o i t a c i f i c e p s l a r e n e g s l e d o m l l as t i n u n o i t a l o s i e g a t l o v n o i t a l o s i e g a k a e l a 0 1 t u p t u o - t u p n i n i m0 0 7c d v t u p t u o o t t u p n i e c n a t i c a p a c p y t5 7f p l a t n e m n o r i v n e e g n a r g n i t a r e p o e s a c g n i t a r e d o n n i m x a m 0 4 - 5 8 c e g n a r e g a r o t s n i m x a m 5 5 - 0 0 1 c ) 9 ( e c n a d e p m i l a m r e h tp y t0 1t t a w / c l a r e n e g t h g i e w t i n up y t7 . 1z o s t i k g n i t n u o m5 1 s m & 6 s m n i pn o i t c n u f 1t u p n i + 2t u p n i - 3t u p t u o + 4n m c 5t u p t u o -
