TO-92

SO-8

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.

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,

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.
