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.
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.
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, 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,
mantaining the same electrical performances. It
needs only 2.2
µ
F capacitor for stability allowing
room and cost saving effect.

(*) Our SO-8 package used for Voltage Regulators is modified internally to have pins 2, 3, 6 and 7 electrically commoned to the die attach
flag. This particular frame decreases the total thermal resistance of the package and increases its ability to dissipate power when an
appropriate area of copper on the printed circuit board is available for heatsinking. The external dimensions are the same as for the
standard SO-8
TEST CIRCUITS
Note: If the Inhibit pin is left floating, the regualtor is in ON mode. However, to avoid any noise picking-up, it is suggested to ground it when
the Inhibit function is not used.
