STANDARD APPLICATION * 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 A, the error associated with this term is negligible in most applications. 3.5 - 7 Vout Vin OM1321STM 3.5 R1 240 IAdj Adjust Co** 1.0 F Cin* 0.1 F R2 OM1321NTM, OM1321STM, OM1321NKM, OM1321SMM, OM1321NMM, OM1321N2M 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 M .350 MIN.M .430M .410M 1 2 3 .020M .115M .160M .020M .080 M .038 MAX.M OM1321SMM .750M .500M .120 TYP.M .100 TYP.M .035M .025M Front View Pin 1 - Adjust Pin 2 - Input Pin 3 - Output Tab - Isolated M .005M .140 .015 OM1321NTM 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 OM1321STM Isolated .140 .075 .415 3 .062 .375 .030 MIN.
