DESCRIPTION
The L4931 series are very Low Drop regulators
available in TO-220, SO-8, DPAK and PPAK
packages and in a wide range of output voltages.
The very Low Drop voltage (0.4V) and the very
low quiescent current make them particularly
suitable for Low Noise, Low Power applications
and specially in battery powered systems.
In PPAK and SO-8 packages a Shutdown Logic
Control function is available TTL compatible. This
means that when the device is used as a local
regulator, it is possible to put a part of the board
in
standby,
decreasing
consumption. It requires only a 2.2
μ
F capacitor
for stability allowing space and cost saving.
