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.
5V with a drive capability up to 50mA.
