1.5A Low Dropout Voltage Regulator
Adjustable & Fix Output
B1586
Description
The Bay Linear B1586 is Monolithic low power 1.5A
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 B1586 Outstanding features include full power usage up
to 1.5Amp of load current internal current limiting and thermal
shutdown. Other fixed versions are also available consult with
factory.
The B1586 is offered in 3-pin TO-220 & TO-263 packages
compatible with other 3 terminal regulators. For 5A Low
dropout Regulator refer to the B1585 data sheet.
