DESCRIPTION
The LD2980 series are very Low Drop regulators
available in SOT23-5L package. The ultra low
drop-voltage and the very low quiescent current
make them particularly suitable for low noise, low
power applications and
systems.
Shutdown Logic Control function is available on
pin n. 3 (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,decreasing
the total power consumption.
