APPLICATION Vout Vin * Cin is required if regulator is located an appreciable distance from power supply filter. ** Co is not needed for stability, however it does improve transient response. R Vout = 1.25 V (1 + 2 )+ IAd j R2 R1 Since IAdj is controlled to less than 100 µA, the error associated with this term is negligible in most applications. 3.5 - 19 OM1324STM R1 240Ω IAdj Adjust Cin* 0.1 µF R2 3.5 OM1324NTM, OM1324STM, OM1324NKM, OM1324SMM, OM1324NMM, OM1324N2M MECHANICAL OUTLINE .425O .200O .190O 1 O .045O .035O .100O .200O 3 O .420O .410O .425O .035 WIDEO FLAT 3 PLCS.O 2 .665O .645O .150O .140O O .537O .527O .350 MIN.O .430O .410O 1 2 3 O ± .020O .115O .160O .020O .080 O .038 MAX.O OM1324SMM .750O .500O .120 TYP.O .100 TYP.O .035O .025O Front View Pin 1 - Adjust Pin 2 - Input Pin 3 - Output Case - Isolated O .005O OM1324STM Isolated OM1324NTM Non-Isolated Front View Pin 1 - Adjust Pin 2 - Output Pin 3 - Input Tab - Isolated Front View Pin 1 - Adjust Pin 2 - Output Pin 3 - Input Tab - Output .140 .015 .140 .140 1 2 .075 .075 .157 .415 3 .062 .375 .030 MIN.
