DESCRIPTION

The L387A is a very low drop voltage regulator in aPentawatt 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
