DESCRIPTION

The L387A is a very low drop voltage regulator in

a Pentawatt

廬

package specially designed to pro-

vide stabilized 5V supplies in consumer and in-

dustrial applications. Thanks to its very low in-

put/output voltage drop this device is very useful

in battery powered equipment, reducing con-

sumption and prolonging battery life. A reset out-

put makes the L387A particularly suitable for mi-

croprocessor systems. This output provides a re-

set signal when power is applied (after an exter-

nal programmable delay) and goes low when
