VERY LOW DROPOUT VOLTAGE (0.2V TYP)  
VERY LOW QUIESCENT CURRENT (TYP.  
50 µA IN OFF MODE, 0.5 mA IN ON MODE,  
NO LOAD)  
OUTPUT CURRENT UP TO 100 mA  
OUTPUT VOLTAGES OF 1.25; 1.5; 2.5; 3;  
3.3; 3.5; 4; 4.5; 4.7; 5; 5.2; 5.5; 6; 8V  
INTERNAL CURRENT AND THERMAL LIMIT  
ONLY 2.2 µF FOR STABILITY  
AVAILABLE IN ± 1% (A) OR ± 2% (C)

SO-8  
SUPPLY VOLTAGE REJECTION: 80db (TYP.)  
TEMPERATURE RANGE: -40 TO 125 °C  
DESCRIPTION  
The LE00 regulator series are very Low Drop  
regulators available in SO-8 and TO-92 packages  
and in a wide range of output voltages.  
TO-92  
The very Low Drop voltage (0.2V) and the very  
low quiescent current make them particularly  
suitable for Low Noise Low Power applications  
and specially in battery powered systems.  
it’s possible to put in stand by a part of the board  
even more decreasing the total power  
consumption. In the three terminal configuration  
(TO-92) the device is even in ON STATE,  
maintaining the same electrical performances. It  
needs only 2.2µF capacitor for stability allowing  
room and cost saving effect.  
They are pin to pin compatible with the older  
L78L00 series. Furthermore in the  
8
pin  
configuration (SO-8) they employ a Shutdown  
Logic Control (pin 5, TTL compatible). This means  
that when the device is used as a local regulator,
