B1581
Description
The Bay Linear B1581 is Monolithic low power 5.0A
Adjustable and fixed NPN voltage regulator that are easy to
use with minimum external components. It is suitable for
applications requiring a well-regulated positive output voltage
with low input-output differential voltage requirements and
output voltage 1.5V, 2.5V, 3.0V, 3.3V, or 5V.
The B1581 Outstanding features include full power usage up
to 5.0Amp of load current internal current limiting and thermal
shutdown. Other fixed versions are also available consult with
factory.
