DESCRIPTION

The LF00 series are very Low Drop regulators

available

in

PENTAWATT,

TO-220,

ISOWATT220, DPAK and PPAK package and in

a wide range of output voltages.

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 battery powered systems.

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
