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.

Notes:
•
The maximum operating input voltage and
output current of the device will be
governed by the maximum power
dissipation of the selected package.
Maximum package power dissipation is
specified at 25°C and must be linearly
derated to zero at T
amb
=125°C.
The following data represents pulse test
conditions with junction temperatures as
indicated at the initiation of the test.
Continuous operation of the devices with
the stated conditions might exceed the
power dissipation limits of the chosen
package.
•
The shut down feature of the device operates
if its temperature exceeds its design limit as
might occur during external faults, short
circuits etc. If the regulator is supplied from
an inductive source then a large voltage
transient, on the regulator input, can result
should the shut down circuit operate. It is
advised that a capacitor (1 F or greater)
should be applied across the regulator input
to ensure that the maximum voltage rating of
the device is not exceeded under shutdown
conditions.
