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.
•
Output current up to 200mA
•
Tight initial tolerance of 2.5%
•
Low 600A quiescent current
•
-55 to 125°C temperature range
•
No external components
•
Internal thermal shutdown
•
Internal short circuit current limit
•
High power SOT223 package
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 350A. 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.
