VERY LOW DROP
TO-92
DESCRIPTION
The L4931 series are very Low Drop regulators
available in TO-220, SO-8, DPAK, PPAK and
TO-92 packages and in a wide range of output
voltages.
The very Low Drop voltage (0.4V) and the v ery
low quiescent current make them particularly
suitable for Low Noise, Low Power applications
and s pecially in bat tery powered system s .
SCHEMATIC DIAGRAM
DPAKPPAK
SO-8
In P PAK and SO-8 packages a Shut down Logic
Control function is av ailable 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 the total power consumption.
It requires only a 2.2 µF capacitor for stability
allowing space and cost saving.
