DESCRIPTION
The LF00 series are very Low Drop regulators
available
in
PENTAWATT,
ISOWATT220, DPAK and PPAK package and in
a widerange of outputvoltages.
The very Low Drop voltage (0.45V) and the very
low quiescent current make them particularly
suitable for Low Noise, Low Power applications
and specially in batterypoweredsystems.
TO-220,
In the 5 pins configuration (PENTAWATT and
PPAK) a Shutdown Logic Control function is
available (pin 2, 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.
In the three terminal configuration the device has
the same electrical performance, but is fixed in
