ZETEX ZMR

ZMR series
Fixed 2.5, 3.3 and 5 volt miniature voltage regulators
Description
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.
The circuit design offers an exceptionally low
quiescent current, only 30µA for the 2.5V
device, ideal for low power applications. The
initial devices in the series regulate to 2.5 or
5V with a drive capability up to 50mA.
Features
The device is designed with space saving in
mind and is available in the small outline SOT23
package. The ZMR250 has expanded its input
voltage range to 22.5V and the ZMR500 has
expanded its input voltage range to 25V;
equalling that of the ZMR25H and ZMR50H
respectively.
The ZMR330 provides a 3.3V output over an
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 Tamb =125°C.
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.
