ZSR SERIES
3.0 to 12 volt fixed positive local voltage regulator
Description
Features
The ZSR Series three terminal fixed positive
voltage regulators feature internal circuit
current limit and thermal shutdown making the
devices difficult to destroy. The devices are
available in a high power surface mount
package, ideal for applications where space
saving is important. The devices are suited to
local voltage regulation applications, where
problems could be encountered with distributed
single source regulation, as well as more
general voltage regulation applications.
