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.
In the 5 pins configuration (PENTAWATT and
PPAK) a Shutdown Logic Control function is
TO-220,
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
the ON state. It requires only a 2.2
μ
F capacitor
for stability allowing space and costsaving.
