DESCRIPTION
The LF00 series are very Low Drop regulators
available in PENTAWATT, TO-220, TO-220FP,
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

VERY LOW DROPOUT VOLTAGE (0.45V)
VERY LOW QUIESCENT CURRENT (TYP.
50 µA IN OFF MODE, 500 µA IN ON MODE)
OUTPUT CURRENT UP TO 500 mA
LOGIC-CONTROLLED ELECTRONIC
SHUTDOWN
OUTPUT VOLTAGES OF 1.25; 1.5; 1.8; 2.5;
2.7; 3; 3.3; 3.5; 4; 4.5; 4.7; 5; 5.2; 5.5; 6; 8;
8.5; 9; 12V
INTERNAL CURRENT AND THERMAL LIMIT
ONLY 2.2 µF FOR STABILITY
AVAILABLE IN ± 1% (AB) OR ± 2% (C)
SELECTION AT 25 °C
SUPPLY VOLTAGE REJECTION: 80db (TYP.)
TEMPERATURE RANGE: -40 TO 125 °C
VOLTAGE REGULATORS WITH INHIBIT
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 µF capacitor for
stability allowing space and cost saving.
