Housed in a SC-74A (SOT-753) package, the part mounts as a standard SOT-23-5 footprint — a common, low-inductance package for board-level voltage monitoring. The small body saves board area on dense mixed-signal PCBs. This removes the supply-chain risk of a forced redesign mid-production.","metaTitle":"TPS3125J18DBVR Simple Reset/Power-On Reset, 1.62V Threshold","metaDescription":"Texas Instruments TPS3125J18DBVR Simple Reset/Power-On Reset IC.

This means you get complementary reset outputs without needing external components like pull-up resistors."},{"question":"How does the TPS3125J18DBVR compare to the TPS3125J12DBVR?","answer":"The TPS3125J18DBVR monitors a 1.62V threshold, while the TPS3125J12DBVR monitors a 1.20V threshold. Both are from the same TPS3125 family with identical package, temperature range, and reset timeout.
