ZSR SERIES
3.0 to 12 volt fixed positive local voltage regulator
Description
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.
The
ZSR
Series
show
performance
characteristics superior to other local voltage
regulators. The initial output voltage is
maintained to within 2.5% with a quiescent
current of typically 350 A. Output voltage
change, with input voltage and load current, is
much lower than competitive devices. The ZSR
devices are completely stable with no external
components.
