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,
maintaining the same electrical performances. It
needs only 2.2µF capacitor for stability allowing
room and cost saving effect.
