Product Summary
The LD2979M28TR is a very low drop regulator available in SOT23-5L.The very low drop-voltage and the very low quiescent current make the LD2979M28TR particularly suitable for low noise, low power applications and in battery powered systems.Shutdown logic control function is available on five pin version (TTL compatible). This means that when the LD2979M28TR is used as local regulator, it is possible to put a part of the board in standby, decreasing the total power consumption.
