ZSR  
SERIES  
2.85 TO 12 VOLT FIXED POSITIVE  
LOCAL VOLTAGE REGULATOR  
DEVICE 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 circuit design allows creation of any  
custom voltage in the range 2.85 to 12 volts. The  
devices are available in a small outline surface mount  
package, ideal for applications where space saving is  
important, as well as through hole TO92 style  
packaging. 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.

Small outline SO8 and SOT223 package  
TO92 package  
2.85 to 12 Volt  
Output current up to 200mA  
Tight initial tolerance  
Low quiescent current  
-55 to 125°C temperature range  
No external components  
Internal thermal shutdown  
Internal short circuit current limit  
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 350µA. 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.

ELECTRICAL CHARACTERISTICS  
Notes:  
1. 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  
3. Maximum power dissipation, for the SOT223 and  
SO8 packages, is calculated assuming that the device  
is mounted on a PCB measuring 2 inches square.  
4. 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 (1µF or greater) should be  
applied across the regulator input to ensure that the  
maximum voltage rating of the device is not  
T
amb=125°C.  
2. 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.  
exceeded under shutdown conditions.
