3 / 23 page www.semtech.com © 2009 Semtech Corp. 3 SC189 Exceeding the absolute maximum ratings may result in permanent damage to the device and/or device malfunction. Operation outside of the parameters specified in the Electrical Characteristics section is not recommended. NOTES: (1) Measured in free convection, mounted on 10mm x 10mm, 2 layer FR4 PCB shown in figure 7 ( for MLPD-UT6 package) and figure 8 ( for SOT23- 5 package) with copper of 1oz for each layer. (2) Tested according to JEDEC standard JESD22-A114-B. (3) For SOT23-5 package, the limit of the maximum power dissiption shown in figure 2 may reduce the maximum output current.
