(*2) The maximum output current performance varies based on a voltage difference between an input voltage and an output voltage, and external components and so on. Regarding detail of this variation, please refer to OPERATIONAL EXPLANATION and NOTE ON USE section. (*3) Design value (*4) Design value for WLP-6-03 (*5) SHORT PROTECTION with LATCH is not available if VOUT1 is 1.2V or less. (*6) "H" = VIN ~ VIN -1.2V, "L" = +0.1V ~ -0.1V 6/28 Document Outline GRM188R61A106ME69 LMK107BBJ106MALT GRM188R61A106ME69 GRM188R60J226MEA0 GRM188R61A226ME15 GRM188R60J476ME15 LMK107BBJ106MALT JMK107BBJ226MA C1608X5R0J226M080AC
