Description

The LEXX is a very low-dropout voltage regulator

available in SO-8, TO-92 packages and over a

wide range of output voltages.

The very low-dropout voltage (0.2 V) and low

quiescent current make it particularly suitable for

low-noise, low-power applications and in battery-

powered systems.

This device is pin-to-pin compatible with the L78L

series. Furthermore, in the 8-pin configuration

(SO-8), it uses a shutdown logic control (pin 5,

TTL compatible). This means that when the

device is used as a local regulator, a part of the

board can be put in standby, decreasing the total

power consumption. In the three-terminal

configuration (TO-92), the device is always in

on-state. It requires a 2.2 µF capacitor for

stability, reducing the component size and cost.
