Description

The LD2979 series are very Low Drop regulators available in SOT23-5L and TO-92. The very low drop-voltage and the very low quiescent current make them 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 LD2979 is used as local regulator, it is possible to put a part of the board in standby, decreasing the total power consumption
