DESCRIPTION
The LD2979 series are very Low Drop regulators
available in SOT23-5Land TO-92.
The very low drop-voltage and the very low
quiescent current make them particularlysuitable
for low noise, low power applications and in
batterypowered systems.
Shutdown Logic Control function is available on
five pin version (TTL compatible). This means
that when the device is used as local regulator, it
is possible to put a part of the board in standby,
decreasingthe total power consumption.
