Description
The LExxAB and LExxC are very low drop voltage
regulators available in SO-8 and TO-92 packages
and in a wide range of output voltages.
SO-8
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 2.2 µF capacitor for stability allowing
room and cost saving effect.
The very low drop voltage (0.2 V) 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
L78Lxx 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,

1. Our SO-8 package used for Voltage Regulators is modified internally to have pins 2, 3, 6 and 7 electrically communed 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.

Note:
If the Inhibit pin is left floating, the regulator is in ON mode. However, to avoid any noise
picking-up, it is suggested to ground it when the Inhibit function is not used.
