FP6137A

fitipower integrated technology lnc. FP6137A/B 3A/2A Bus Termination Regulator Description The FP6137A/B linear regulator is designed to provide the transient peaks up to 3A/2A sourcing or sinking capability for DDR SDRAM bus termination application. The output voltage can track half of input power by two external voltage divider resistors. The FP6137A/B provides current limit in both sourcing/sinking mode and thermal shutdown function which protects the excessive heating due to high current and high junction temperature. The FP6137A are available in SOP-8 (exposed pad), TO-252-5 and TO-263-5 packages. The FP6137B are available in the SOP-8 (fused), SOP-8 (exposed pad) and TO-252-5 packages.
