TPS610987DSER Description

The TPS610987DSER is an ultra-low power solution for products powered by either a one-cell or two-cell alkaline, NiCd or NiMH, one-cell coin cell, or one-cell Li-Ion or Li-polymer battery. It integrates either a Lowdropout Linear Regulator (LDO) or a load switch with a boost converter and provides two output rails. The boost output V(MAIN) is designed as an always-on supply for the main system, and the LDO or load switch output V(SUB) is to power peripheral devices.
