INFORMATION
ORDERING NUMBER :
L387A
Pentawatt
The L387A is a very low drop voltage regulator in
a Pentawatt
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
DESCRIPTION
power is removed, inhibiting the microprocessor.
An hysteresis on reset delay capacitor raises the
immunity to the ground noise.
