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.

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.
