ZMR series  
Fixed 2.5, 3.3 and 5 volt miniature voltage regulators  
Description  
The ZMR series of three terminal fixed The device is designed with space saving in  
positive voltage regulators feature internal mind and is available in the small outline SOT23  
current limit and will shut down under package. The ZMR250 has expanded its input  
thermal overload conditions making the voltage range to 22.5V and the ZMR500 has  
devices difficult to destroy.  
expanded its input voltage range to 25V;  
equalling that of the ZMR25H and ZMR50H  
respectively.  
The circuit design offers an exceptionally low  
quiescent current, only 30µA for the 2.5V  
device, ideal for low power applications. The The ZMR330 provides a 3.3V output over an  
initial devices in the series regulate to 2.5 or input range of 5V to 24V.

Note:  
1. The maximum operating input voltage and output current of the device will be governed bythe  
maximum power dissipation of the selected package. Maximum package power dissipationis  
specified at 25°C and must be linearly derated to zero at T  
=125°C.  
amb  
2. The following data represents pulse test conditions with junction temperatures as indicated  
atthe initiation of the test. Continuous operation of the devices with the stated conditions  
mightexceed the power dissipation limits of the chosen package.  
3. Maximum power dissipation for the SOT23 package, is calculated assuming that the device  
ismounted on a ceramic substrate measuring 15 x 15 x 0.6mm.
