FIXED 2.5 AND 5 VOLT  
MINIATURE VOLTAGE REGULATORS  
ISSUE 4 - MARCH 2002  
ZMR SERIES  
DEVICE DESCRIPTION  
FEATURES  
The ZMR series of three terminal fixed  
positive voltage regulators feature internal  
current limit and will shut down under  
thermal overload conditions making the  
devices difficult to destroy.  
Small outline SOT23 package  
•
•
•
•
TO92 package  
2.5V and 5V output  
22.5V maximum input voltage  
(ZMR25H)  
The circuit design offers an exceptionally  
low quiescent current, only 30µA for the 2.5  
volt device, ideal for low power applications.  
The initial devices in the series regulate to  
2.5 or 5 volts with a drive capability up to  
50mA, however, the flexible design will  
allow other voltage selections to be made.  
25V maximum input voltage (ZMR50H)  
Output current up to 50mA

Very low Quiesent current (30µA)  
Unconditionally stable  
Other output voltages possible  
Internal short circuit current limit  
The device is designed with space saving in  
mind and is available in the small outline  
SOT23 package. The device is also available  
in through hole TO92 package.

Note:  
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 Tamb =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.  
3. Maximum power dissipation for the SOT23 package, is calculated assuming that the device is  
mounted on a ceramic substrate measuring 15 x 15 x 0.6mm.
