L4979D Overview
L4979D and L4979MD are low dropout linear regulators with microprocessor control functions such as low voltage reset, watchdog, on/off control. Typical quiescent current is 100 µA in Datasheet - production data very low output current mode and enabled regulator. The devices drop to 6 µA with not enabled regulators.
