STANDARD 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 - 3 OM1320STM 3.5 R1 240Ω IAdj Adjust Cin* 0.1 µF Co** 1.0 µF R2 OM1320NTM, OM1320STM, OM1320NKM, OM1320SMM, OM1320NMM, OM1320N2M MECHANICAL OUTLINE .425M .200M .190M 1 M .045M .035M .100M .200M 3 M .420M .410M .425M .035 WIDEM FLAT 3 PLCS.M 2 .665M .645M .150M .140M .537M .527M M .350 MIN.M .430M .410M 1 2 3 M ± .020M .115M .160M .020M .080 M .038 MAX.M OM1320SMM .750M .500M .120 TYP.M .100 TYP.M .035M .025M Front View Pin 1 - Adjust Pin 2 - Input Pin 3 - Output Case - Isolated M .005M .140 .015 OM1320NTM 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 1 2 .075 .157 OM1320STM Isolated .140 .075 .415 3 .062 .375 .030 MIN.
