s FAST DYNAMIC RESPONSE TO LINE AND
LOAD CHANGES
DESCRIPTION
The LD2980 series are very Low Drop regulators
available in SOT23-5L and SOT-89 packages.
The ultra low drop-voltage and the very low
SOT23-5L
SOT-89
quiescent current make them particularly suitable
for low noise, low power applications and in
battery powered 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.
