ZMR Series
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; equaling that of the ZMR25H and ZMR50H
respectively.
The ZMR330 provides a 3.3V output over an input range of 5V to
24V.

Notes: 4. 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 T
5. 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.
6. Maximum power dissipation for the SOT23 package, is calculated assuming that the device is mounted on a ceramic substrate measuring 15x15x0.6mm.
