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 SOT223 Package suffix - G  
maintained to within 2.5% with a quiescent  
current of typically 350A. Output voltage

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  
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 (1F 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.  
derated to zero at T  
=125°C.  
amb  
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.
